Abstract

Existing approaches to multiplexed coded aperture imaging (i.e., cyclic redundant, uniformly redundant, pseudonoise, etc.) methods are based upon encoding schemes that employ 2-D masks consisting of transparent and opaque regions. These approaches have optical efficiencies that are typically ~50%, and they require a set of encoding masks containing ~N members, where N is the number of image pixels to be encoded.
