Computerized design and generation of space-variant holographic filters. 1: System design considerations and applications of space-variant filters to image processing.

A computerized optical system has been constructed for the design and generation of space-variant holographic filters. Special considerations of the computerized design of the space-variant filters and the operation and performances of the system are addressed and discussed. The system was experimentally employed to generate holographic optical filters for the optical implementations of Hough transform, coordinate transformations, etc. Experimental performances of the generated space-variant filters are evaluated and discussed.
