speed will be 2-5 lines/second for smooth surfaces. For rougher surfaces
a lower scan speed may be needed.
A typical resolution of 256 pixels/line provides good resolution and
speed. Increasing the resolution will improve image quality but will
require longer imaging times.
One good option is to scan a large region at low resolution and high
speed, and then to zoom in on a region of interest for a high resolution
scan at lower speed. After completing the large scan, use the Offset and
Size values in the Scan and Motor window to adjust the scan to cover
the region of interest. Increase the Resolution, decrease the Speed, and
re-scan the zoomed region.
