Abstract

The techniques used for storing matched filters in image processing units of the optical matched filter image correlator (OMFIC) type determine to a large extent the capacity and discrimination of the complete system. Coherent and non-coherent addition of images for overlayed matched filter recording are investigated and reported upon. Results are related by performance in the areas of diffraction efficiency and signal-to-clutter measurements. Dichromated gelatins are used as matched filter recording media and the results compared with silver salt photographic materials. Finally, a formula is derived for matched filter capacity and the analysis extended to the case where the medium sets the resolution for matched filter recording.
