Abstract

Two systems serve as examples of surface evaluation by means of laser scanners. One utilizes conventional image-processing methods in a hazardous environment. The other uses analysis of scattered light to extract the signature of the surface flaws. A general check list for optical design questions illustrates similarities and differences in the two applications.
