TSI Phase Doppler Particle<br />
Analyzer/Laser Doppler Velocimeter<br />
(<strong>PDPA</strong>/<strong>LDV</strong>) systems have introduced<br />
a broad array of technical innovations<br />
that revolutionized particle size and<br />
velocity measurements. We originated<br />
the single-receiver, three-detector<br />
scheme; launched optical fiber technology<br />
for transmitter and receiver systems;<br />
and offered the first digital signal<br />
processors for accurate particle size<br />
and velocity measurements.<br />
We also introduced two signal processing<br />
techniques for measuring velocity<br />
and size; pioneered the concept of<br />
adapting processing algorithms to match<br />
signal characteristics and the information<br />
needed; and were first to utilize<br />
burst centering, dynamic sampling rate<br />
optimization and SNR-based burst<br />
detection. Moreover, we introduced<br />
unique, innovative techniques for validating<br />
data and removing trajectory<br />
dependent influences on particle<br />
size measurements.<br />
Introducing<br />
a Revolutionary<br />
<strong>PDPA</strong>/<strong>LDV</strong> System<br />
• a quantum leap in capability, performance and ease-of-use<br />
• the most powerful velocity and size measurement system available<br />
• concepts and ideas covered by four separate patents<br />
This unique <strong>PDPA</strong>/<strong>LDV</strong> system combines the following subsystems to provide<br />
unparalleled performance and operating ease:<br />
• New FSA Multi-bit Digital Processor<br />
• New fiberlight TM Multi-color Beam Separator<br />
• New fiberoptic transmitting and receiving probes<br />
• New fiberoptic couplers<br />
• New PDM multi-color scattered light separation and photodetector system<br />
• New EIC Multi-channel External Input Device<br />
Thus, TSI <strong>PDPA</strong>/<strong>LDV</strong> systems have<br />
long been the standard for flow and<br />
particle diagnostics instrumentation.<br />
Continuous innovation made them the<br />
most versatile, accurate <strong>PDPA</strong>/<strong>LDV</strong><br />
systems available.<br />
Now, TSI takes the next step...
