Paper Abstract

An opto-electronic hybrid system for automated near real-time processing of microscopic samples has been developed. Spatial frequency plane filtering techniques adapted to a commercial microscope are used for fast preprocessing. The noise problem was substantually reduced by use of either a moving point-like light source or by a spatially extended light source. Calculations and experiments show the conditions under which the influences of the extension of the source for both methods onto high-pass, band-pass and gradient filtering can be neglected. The system has been used for the automated evaluation of cytological smears and for detection of asbestos fibers in membrane filters.
