Abstract

Fourier transforms of diatom specimens are studied for the purpose of making improved spatial filters for use in a real-time coherent optical recognition system. The system consists of directing a laser beam into an interference contrast microscope to produce a real, magnified coherent image of the specimen to be recognized. This technique provides a method of adjusting low frequency attenuation for image enhancement over a continuous range. Examples of results are shown.
