Paper Abstract

An optical/video processing system is described together with applications to satellite and aerial survey imagery. Diffraction pattern sampling, spatial filtering and holographic filtering can be implemented. The optical system is of very high quality, with diffraction limited performance for LANDSAT format transparencies and negligible coherent noise. The use of CCTV equipment in both diffraction and image planes allows interactive processing to be carried out together with further simple non-linear operations, such as grey level slicing and contouring.
