2-28 Chapter 2 Operation . - -, , ". Other mountings for the BSD may require different settings for Topo - these may be defined by setting the individual segments to the required values and pressing the Defme Topo buttons. These settings will then be used for future selections of Topo. There are two other fields on this panel. The Four Quadrant BSD: Gain field indicates which range the amplifier is currently on. it is set automatically from the signal level controls and need not be changed by the user. The Four Quadrant BSD: Fast field selects the bandwidth from the detector. it should be set to FAST for normal visual scan rates and to SLOW for slower scan rates and photo recording. 2.4.4. Scan Rate and Noise Reduction Scan Rate There are 4 scan rates available as standard on the Stereoscan 440. They are represented by the Pixel Average parameter which can have values 1. 4. 16 or 128. The scan rate is usually changed using the scan rate icons. but there are also options on the Scanning menu and on the Noise Reduction panel to do the ~. Noise Reduction The Noise Reduction panel is selected with the right mouse button on the Filter icon. It allows the type of noise reduction to be selected (Line average or Frame average) as well as the number of lines or frames the averaging is to be performed over. In addition the freeze options allow the current zone to be frozen or unfrozen. The Freeze At EDd option freezes the zone when the image acquisition has completed (detennined by the number of frames in frame average, or just I frame if line average is selected). There is one important difference between line and frame average. In line average mode the same noise reduction is applied to all the active zones. But for frame average it is possible to set different frame counts for each zone. .. The use of noise reduction is explained further in Chapter 3 Advanced Operation 2.4.5. Live Line Scanning The Line option on the Scanning menu selects live line scanning. In this mode a single line of the image is scanned repealedlY and a profile of that line is displayed. The rest of the image is frozen during line scanning and a line cursor is used to select the line to be scanned. Stereoscan 440 Operator Manual
The profile's appearance is controlled through the pop-up menu associated with it. The following fields are used:- X Scale - determines the width of the profile (displays every nth pixel) Y Scale - detennines the height scaling of the profile Static! Active - Determines whether the profile is redrawn at the end of each line scan Copy - Link for transfer of data to spreadsheets. Selecting normal scanning will deselect line scanning One special case of live line profiling exists when the system is also in split screen scanning. In this mode two traces are displayed on the profile, the usual green trace represents zone 0 and a red trace represents zone I (the left and right hand sides of the image respectively). 2.4.6. Spot Mode Spot mode is selected from the Scanning menu. On selection the image is frozen and a crosshair cursor appears to indicate the beam position. The cursor may be moved by dragging with the mouse. Selecting normal scanning deselects spot mode. 2.4.7. Histograms Selecting the Histogram option on the Image menu displays a grey level histogram of the image, that is a bar chart showing the number of pixels at each grey level. A pop-up menu controls the appearance of the histogram with the following fields:- . . . . Bin Width - Sets the width of each bin on the display Height - Sets the height of the histogram display Source - Selects the source of the histogram data Sample, Start and Stop - Control the updating of the histogram data Copy - Link for transfer of data to spreadsheets. The source can be defined as either the stored image, the current zone or a specified zone. If the stored image is selected then the histogram data will only be updated when the Sample option is selected. If the data source is a zone, then the Start and Stop options conb"Ol the updating of the data. The source of the image is important because stored data has been processed by the input LUT and the noise reduction, whereas the zone data is entirely unprocessed. Stereoscan 440 Operator Manual
