Abstract
Experiment 17.1: Digital Scanning. For a 128x128 image there are 16,384 pixels, and with a dwell time of 100 μsec/pixel the image takes 1.6 sec to acquire (frame time). A 512x512 image contains 262,144 pixels and, for the same dwell time, takes 26 sec to acquire. Compared to a 1000-line analog image (the usual SEM Polaroid), a 512x512 image of the same size is very similar but exhibits barely percetible lines and pixels.
