Abstract
Although laser scanning is a relatively new technology, it has already found many applications in recording systems, OCR, film readers and data digitizers. A primary reason is that the monochromaticity and coherence of the laser beam makes it possible to focus the wavefront to a diffraction limited point image which then becomes the recording or analyzing spot.
