Abstract

A digital-optical hybrid system composed of a computer and a coherent optical filtering system is successfully applied to perform a real-time correlation of aerial stereo photographs. A LOLV (Liquid Crystal Light Valve) as an incoherent-to-coherent convertor and a thermoplastic photoconductor material for holographic recording of MSF (Matched Spatial Filter) are used, and a sharp correlation peak with a good SNR is obtained.
