Applications and Testing Results of the Optical Power Spectrum Analyzer

摘要

A Coherent Optical Subsystem (COSS) for scanning photographic imagery is interfaced to a minicomputer forming an Optical Power Spectrum Analyzer (OPSA) designed for applications of feature classification and 'image quality' measures on a production basis. Applications are directed at finding non-correlation areas of aerial imagery intended for use in automated photo-grammetric information and the overall utility of the image. (Author)
