Abstract

A differential amplitude scanning optical microscope (DASOM) is described. The system, which uses a simple optical and electronic arrangement, is capable of detecting variations in optical reflectivity of 9 × 10⁻⁶ in a 10kHz bandwidth. Results of surface studies of polished stainless steel and of natural diamond are presented.
