ABSTRACT:
An object (12) is raster scanned with a small, localized beam of laser light (22) and the backscattered radiation therefrom is monitored by a plurality of detectors (44). Each of the detectors (44) monitors a different characteristic of the backscattered radiation and an arithmetic operation is performed on the output of the detectors to provide a single composite video signal with enhanced contrast.
