4.7.3 Scan speed
The signal-to-noise ratio can be substantially
improved by reducing the scanning speed to an
acceptable level and averaging over several scans
(i.e. with an Average Number greater than 1 in
the "Scan Control" window).
Use the Scan Speed slider on the Speed panel
to set the slowest acceptable scanning speed.
The corresponding pixel scanning time (Pixel
Time) and the total scanning time (Scan
Time) are shown in the dialog box.
In the Number text box of the Pixel Depth,
Scan Direction & Scan Average panel enter
the number of measurements to be averaged.
☞
Image optimization can be effected
much faster if you select a smaller
frame, since less data have to be
processed.
