VALYN V.I.P. THE VALYN MULTI-BEAM VISAR 

2 

VALYN’s MULTI-BEAM VISAR 6 

Ideal for Multiple Point Measurements 

In addition to the VISAR Interferometer Module, the System uses a separate Beam Module for each “beam”, i.e., 

each point to be measured simultaneously by the VISAR. All beams pass together through the same VISAR 

interferometer. Then they are separated and delivered to their assigned Beam Modules via optical fibers. Each 

Beam Module contains the following equipment. 

% All electronic processing and other heat 

producing elements are contained in the BEAM 

MODULES, making the VISAR Interferometer 

extremely stable. 

% For convenience and ease of light alignment, 

optical fibers bring light fringe signals from the 

VISAR interferometer to the Beam Modules. 

% A Low-Noise POD-4 Photomultiplier Unit 

senses the four quadrature fringe signals from the 

point being measured by the Beam Module. The Unit 

houses 4 PMTs with 1 ns risetime, and has fiber optic 

inputs, electronic wiring, a front panel high/low gain 

switch, and front panel light intensity controls for 

equalizing PMT outputs. PMTs with 0.5 ns risetimes 

are also available. 

% Low-Noise Compact Beam Intensity Monitor 

Photomultiplier Unit includes a PMT Housing with 

a High/Low Gain Switch, Fiber Optic Input with 

Light Intensity Control, and Electronic Wiring. It is 

contained in the Main Beam Module only, and serves 

as the diagnostic for all the beams. 

% A pair of Differential Amplifiers, each with X10 

Gain and DC to 1.3 GHz Bandwidth, complete with 

power supply, combine the four quadrature signals 

from the PMTs into the two 90° out-of-phase signals 

required for accurate data reduction. 

The inside of the VISAR Interferometer Module is 

fitted with a Fiber Optics Platform, polarizing 

beamsplitters and lenses, five X-Y-Z Fiber Positioners 

to pick up the interferometer’s output signals into 

optical fibers, and a high-efficiency beamsplitter to 

split off light for the Beam Intensity Monitor. 

6 Patented - #5,870,192 

% A regulated high-voltage DC power supply 

provides the negative high voltage required for the 

Module’s PMTs. The supplied voltage is adjustable 

via a front panel potentiometer, and voltage or 

current is displayed on a digital panel meter. 

% A Module-contained Digital Real-Time 

Alignment Monitoring Oscilloscope (AMO), 

together with V.I.P.’s specially modified BNC “T”s, 

allows the user to easily optimize the signals to be 

recorded right up to shot time, resulting in greater 

reliability and accuracy of VISAR data. 

% Beam Modules can be latched together for 

stacking, and the stack rests on a base pedestal. 

Module dimensions are 18 cm (7") high x 38 cm (15") 

deep x 56 cm (22") wide. The Modules weigh about 

15.5 kg (34 lb) each. 

% Interferometer Specifications are the same as in 

the VCV-03 and VCV-04 CLASSIC VISARs listed 

on Page 5. Details and Prices - Contact Valyn V.I.P. 

Beam Modules can be purchased separately.

VALYN V.I.P. THE VALYN MULTI-BEAM DOUBLE-DUTY ORB VISAR 

VALYN’s MULTI-BEAM DOUBLE-DUTY ORB VISAR 7 

Multiple Point Measurements Using Both PMTs and Streak Cameras Simultaneously 

In addition to all of the features of the VALYN MULTI- 

BEAM VISAR, described on page 2 of this catalog, this 

VALYN MULTI-BEAM DOUBLE-DUTY ORB VISAR, 

the most powerful VISAR in the world, comes with a 

special harness composed of 196 matched optical fibers. 

This special harness, together with the normal 

Photomultiplier Units, supplied in all of the VALYN 

VISARs, and a Streak Camera (not supplied by Valyn 

V.I.P.), will simultaneously record the data from one’s 

experiment with the wide sweep of the Photomultiplier 

Units, with 500 or 1000 ps time resolution, and the 

extremely good time resolution, such as 100 ps or 

better, of the Streak Camera. And, it does it for up to 

seven measurement points at a time! 

7 Patented - #5,481,359, #5,870,192 

Many VISAR experiments can benefit from 

simultaneous Streak Camera and PMT recordings - a 

Streak Camera to resolve very fast events, such as the 

shape and rise-time of a strong shock wave, for example, 

and much longer-lasting PMT records to measure 

longer-term events, such as the arrival of secondary 

waves or edge effects. Also, the PMT data makes a 

good backup and trigger diagnostic in case the main 

event of interest is missed by the Streak Camera 

because of its short time window.

VALYN V.I.P. THE VALYN DOUBLE-DUTY ORB VISAR

VALYN’s DOUBLE-DUTY ORB VISAR 8 

Single Point Measurements Using Both PMTs and Streak Camera Simultaneously 

Valyn International’s Double-Duty ORB (Optically Recorded Bull’s-Eye) VISAR is especially designed for simultaneous 

streak camera and photomultiplier recording (Double-Duty) with time resolutions to 0.1 ns (streak camera), and 1.0 ns or 0.5 

ns (PMTs). Streak cameras provide unsurpassed time resolution, but only for a very limited time window. Simultaneous 

PMT recordings provide a greatly expanded time window at a lessor time resolution, often an extremely valuable 

addition to the streak camera record. The ORB’s streaking of the bull’s-eye of the VISAR interferometer fringe pattern 

allows the PlotData VISAR Data Reduction Program to be used on both the streak camera and the PMT records. 

For Flying Foil Experiments, 

Valyn’s DOUBLE-DUTY ORB 

VISAR has the same patented 

ease-of-use features as the VALYN 

CLASSIC VISARs. However, it is 

tailored for measurements of thin 

foils accelerated to very high 

velocities by a sudden deposition 

of energy, or for measurements of 

specimens impacted by such foils. 

Special features include the 

following. 

% Instead of relatively thick delay 

etalons, two thin etalons provide 

nine easily accessible Velocity-Per- 

Fringe sensitivities covering the 

needed high VPF range of 1 to 10 

km/s/Fr. This compares with the 

0.18 to 2.6 km/s/Fr range of the 

VALYN VCV-03 CLASSIC 

VISAR. Only high VPFs allow 

extremely fast time response 

VISAR measurements, because 

the intrinsic risetime of the 

VISAR interferometer, which is 

equal to the delay time in the 

delay leg of the interferometer, is 

small only for high VPFs. The 

delay times for the 1 to 10 

km/s/Fr range are 260 to 26 ps. 

% Many flying foil experiments 

involve very small foil diameters, 

such as 1 mm or less. These 

require extremely small laser spot 

diameters, and very accurate 

8 Patented - #5,481,359 

positioning of the spot on the foil. 

A specially designed Flying 

Foil/VISAR Interface (FFVI) is 

included with each DOUBLE- 

DUTY ORB VISAR to meet these 

requirements. The FFVI holds a 

special small-spot Fiber Optic 

Probe, which, combined with the 

FFVI’s own optics, makes spot 

sizes down to only 0.1 mm on the 

foil. This compares with the 0.6 

mm spot diameter of a standard 

probe. The FFVI also has a 

magnifying periscope for easy 

straight-on viewing of the spot 

position on the foil. It also 

provides micrometer XYZ 

adjustments for positioning and 

focusing. Also, the FFVI protects 

the probe from damage by the 

flying foil. 

% Optical fibers pick up the 

VISAR interferometer’s fringe 

signals and transmit them to the 

streak camera and to the 

photomultipliers. Most of the 

light is automatically partitioned 

to the streak camera, where it is 

needed to compensate for the 

larger quantum shot noise in the 

faster streak camera data. Valyn 

V.I.P. furnishes the streak camera 

fibers already lined up to form the 

input slit of the streak camera. 

The slit width is only 100 :m. 

% Convertibility - The VALYN 

DOUBLE-DUTY ORB VISAR 

makes use of the very successful 

VALYN VISAR designs. The 

ORB VISAR can be converted 

easily to include the full VCV-04 

VALYN CLASSIC VISAR 

Velocity-Per-Fringe Range in 

addition to the ORB VPF Range, 

by purchasing the necessary larger 

delay etalons of the VCV-04 

VALYN CLASSIC VISAR. This 

makes it a Triple Option 

Research VISAR with a VPF 

range of 0.1 km/s/Fr to 10 

km/s/Fr, encompassing at least 

twenty VPFs, each easily 

accessible in less than a minute. 

Valyn’s DOUBLE-DUTY ORB 

VISAR includes everything except 

the laser, the streak camera and its 

accessories, and, for double-duty, 

the fast digitizing oscilloscope.

WINDOWS-BASED VALYN VISAR DATA REDUCTION PROGRAM 

The windows-based program is called PlotData 2.5, 

written by David E. Wackerbarth of Sandia National 

Laboratories. PlotData operates on a National 

Instruments’ LabVIEW software platform, and 

allows the user to capture waveform data over a GPIB 

bus. PlotData can both import and export several 

types of binary waveform files including, but not 

limited to Tektronix.wmf files and xy pair ASCII files. 

Waveform manipulation includes numerous math 

functions, integration, differentiation, smoothing, 

truncation, and other specialized routines for reducing 

VISAR data.

VALYN V.I.P. MULTI-BEAM SPLITTER, DIFF. AMPS, & ETALONS 

ADJUSTABLE MULTI-BEAM SPLITTER and FIBER COUPLER 10 (AMBS/FC-2) 

Valyn V.I.P.’s unique Adjustable Multi-Beam Splitter and Fiber Coupler (AMBS/FC-2) splits a laser beam 

into several optical fibers for use in VISAR instrumentation, or for other purposes. Its features include: 

% Modular Construction - Allows addition or 

deletion of Splitter Modules to attain the number 

of output fibers desired. More modules can be 

purchased as more outputs are needed. 

% Splitting Ratio - Easily variable for each output 

fiber without wasting light. 

% Input Powers - Up to 10 W continuous 

How it Works — The AMBS consists of disks, or 

modules, each of which has an output optical 

fiber carrying the split-off light. To attain the 

desired split, the entire module is rotated about the 

laser beam axis. The user has complete control of the 

amount of light split off by each module. 

DIFFERENTIAL AMPLIFIERS 

DIFFERENTIAL AMPLIFIERS for VISARs are 

available at Valyn V.I.P. These amplifiers are 

very robust, and are ideal for use with Push-Pull 

VISARs. 

They come in the same configuration as before 

(except slightly thicker), and use the same supply 

voltages (± 15 VDC), as the older Comlinear 

Differential Amplifiers formerly used in most 

VISARs.

Focal Length - Distance in mm from probe face to target. 

Average - Relative amount of light you can expect any 

probe of that type to return, assuming it is focused on a 

diffuse surface like the dull side of aluminum foil. 

Lowest - Smallest amount of light return we accept in 

probes of that type that we send to our customers. 

Depth of Field - Distance a target can travel before going 

out of probe’s field of view 

Fiber Type - Return fiber, or collection fiber, used by our 

probes - 300 or 1000 :m. 

An ST Connector Board connects the Probe's fibers to 

permanent fibers leading to the laser and the VISAR 

interferometer. 

The VALYN CLASSIC VISARs are compatible with the Valyn 

V.I.P. Fiber Optic Probe FOP-1000, which makes use of a 

reflected-light fiber with a core diameter of 1000 :m. Its 

depth-of-field is 12 mm. 

Nearly any VISAR can use Valyn V.I.P.’s Fiber Optic Probe 

FOP-300 with 300 :m reflected-light fiber. Its depth-of-field is 

5 mm.

VALYN V.I.P. MULTI-BEAM ROSETTE FIBER OPTIC PROBE 13 

Valyn V.I.P.’s Multi-Beam Rosette Fiber Optic Probe 13 - Valyn International’s MULTI-BEAM VISARs 

measure the velocities of up to seven points of interest simultaneously. Customers are very enthusiastic! 

VALYN MULTI-BEAM VISARs use a separate 

single-beam fiber optic probe for each measured 

point. The points can be located nearly anywhere 

desired, as long as they are separated by at least the 

diameter of the probe. 

However, in some experiments researchers need to 

measure points much closer together. To answer 

this need, Valyn V.I.P. has developed a Multi-Beam 

Rosette Fiber Optic Probe (RFOP), to monitor up to 

seven closely-spaced points simultaneously. 

(Fig. 1). 

13 Patented - #5,202,558 

12 

Valyn V.I.P.’s patented probe body provides easy 

alignment and good light efficiency. Each probe has 

a rosette of seven fibers with 50 :m cores for 

furnishing the laser light (Fig. 2). The light from the 

fiber ends is imaged by a rosette-projecting lens 

onto the target. Available with Standard (Flexible) or 

Plug & Play (Aluminum Body). 

Some of the reflected light is collected and imaged 

onto another rosette, this one of 300 :m fibers. 

Each reflected-light fiber collects light from only one 

point on the target. Cross-talk between points is 

minimal.

Probe Characteristics 

Although RFOPs are made for illuminating and 

capturing light from seven points at once, they also 

measure any number of points less than seven. For 

fewer than seven points, only the desired fibers are 

connected to the laser light source. 

The size of the point pattern on the target can be 

changed by the easy replacement of the probe’s 

Incident-Light Focusing Lens (IFL). The 

characteristics of the probe when used with the six 

available IFLs are summarized in Table I. The 

available rosette diameters of 1 to 4 mm should be 

very useful for measuring the flatness of flying foils 

accelerated to high velocities.

Probe Use Recommendations 

An XYZ probe-positioning fixture with fine 

adjustments is desirable to position the probe’s spots 

on small targets. 

The Valyn V.I.P. Rosette Fiber Optic Probe’s easily 

replaceable Incident-Light Focusing Lens protects the 

rest of the probe from damage by the miniature but fastmoving 

targets. Spare IFLs should be on hand. 

The target should have a diffusely reflecting surface. 

Tests with specular target surfaces have shown that 

the light reflected from them seldom finds its way 

back through the probe’s optics as intended.

VALYN V.I.P. Fiber Optic Probe Mount & ST Connector Board 

Valyn V.I.P.'s Fiber Optic Probe Mount, Model 

FOPM-76 is a ready-made universal mount for 

holding a Fiber Optic Probe at the correct position 

with respect to the specimen's reflecting surface. It 

consists of a post on which an arm with an elbow is 

mounted. 

The probe is held at the end of the arm. The post is 

anchored near the outside edge of the specimen plate 

with a 1/4-20 bolt. The arm with the elbow allows 

the probe to be located anywhere from 19 to 76 mm 

from the post position. Mounts are available with 

either 30 or 60 mm nominal stand-off distance. 

Valyn V.I.P. Fiber Optic ST Connector Boards 

Valyn V.I.P.’s Fiber Optic Probes come with ST 

fiber connectors on their fiber ends to make 

replacing of probes a quick and easy task. Each 

fiber connection is made through an ST mating 

sleeve which holds the two fiber ends precisely 

aligned. 

VALYN MULTI-BEAM VISARs are supplied with 

a Valyn V.I.P. Fiber Optic ST Connector Board 

(analogous to the formerly used Fiber Optic Splice Board) 

having 14 ST mating sleeves - two for each of seven 

possible Fiber Optic Probes.

Fiber Optic Probe Mount 

Vacuum-Tight Fiber Optic Feed-Throughs 

Many VISAR measurements take place in a modest 

vacuum environment of perhaps 10 to 100 miliTorr. 

Special Valyn-V.I.P.’s modified ST mating sleeves 

which are vacuum-tight are now available to allow 

optical fibers to pass into and out of a vacuum 

chamber. In this case, a port hole or a wall of the 

vacuum chamber becomes the “Fiber Optic ST 

Connector Board,” with the vacuum-tight Valynmodified 

ST mating sleeves screwed into threaded 

holes in the chamber. 

ST Connectors 

Valyn V.I.P. offers ST Connectors Installed and 

Ready to Use on all of our Fiber Optic Probes, 

Cables, and Harnesses. ST Connectors are a safe, 

efficient and easy way to connect one cable to 

another. 

We are proud to offer this valuable product and 

service to our customers at a competitive price. 

Please call Valyn V.I.P. for more information.

VALYN V.I.P. MINI- and :-SPOT SIZE FLYING FOIL/VISAR INTERFACE 

MINI- AND :-SPOT SIZE FLYING FOIL/VISAR INTERFACE - Because of small foil sizes and varying velocity 

over the foil surface, VISAR measurements of flying foils often need smaller laser spot diameters on the foils than 

the 600 :m of the standard Valyn V.I.P. Fiber Optic Probes. Valyn International’s Mini- and :-Spot Fiber Optic 

Probe System, made by Valyn V.I.P., provides much smaller spots, as well as micrometer position adjustment, a 

magnified straight-on view, and protection of the probe from the flying foil. This system comes with the VALYN 

DOUBLE-DUTY ORB VISAR, and can also be purchased separately.

Some of our customers are concerned about the 

amount of light they may get back during an 

experiment. It is hard to tell until you plug the probe 

in and turn on the laser. For background information, 

the table below is based on measurements using the dull 

side of aluminum foil as a target. 

DEFINITIONS 

Focal Length - the distance in mm from the probe face 

to the target. 

Average - the relative amount of light you can expect 

any probe of that type to return, assuming it is focused 

on a diffuse surface like the dull side of aluminum 

foil. 

30 

Valyn V.I.P. produces many different kinds of probes. 

Some give excellent light return in exchange for a 

short depth of field, some give just the opposite, and of 

course, there are degrees in between the two extremes. 

This table will help you order more precisely what you 

need for your experiments. 

Lowest - the smallest amount of light return we accept 

in probes of that type that we send to our customers. 

Depth of Field - the distance a target can travel before 

going out of the probe’s field of view. 

Fiber Type - the return fiber, or collection fiber, used by 

our probes - 300 or 1000 :m. 

Fiber Type - 300 :m (Core Size) 1000 :m 

Focal Length Depth of Field Average Lowest Average Lowest 

30 mm 5 mm/12 mm 4.5% 4.0% 7.8% 5.9% 

60 mm 10 mm/25 mm 1.3% 0.8% 2.6% 2.0% 

120 mm 20 mm/50 mm 0.4% 0.3% 0.7% 0.5% 

150 mm 25 mm/63 mm 0.09% 0.05% 0.4% 0.2% 

These values are for probes with 1.5 m fibers. Probes with 1000 :m fibers of lengths longer than 1.5 m will return less 

light than the table indicates because of the attenuation of light in the plastic fiber. The 300 :m probes do not have this 

problem since they use glass fiber.
