Abstract

Optical prefilters, which make use of the double-refraction effect in crystalline quartz, reduce the amount of aliasing artifacts in the displayed image of a video system. This paper describes anew class of optical prefilter that produces different amounts of blur for different colors. The chromatic variation is obtained by placing a polarization retarder between two quartz crystals. This type of filter is useful with sensors that have unequal pixel densities in the three sensed colors.
