Abstract:

This Final Report addresses key issues for development of a multiple aperture imaging system which could perform high resolution imaging at very long ranges for surveillance or discrimination. Multiple aperture systems can be used to realize extremely large optical apertures required for long-range, high- resolution systems. Our concept, which makes use of an array of intensity sensing subapertures photon buckets, requires the simplest and potentially lowest cost hardware of any multiple aperture imaging system. The work described in this report is divided into three parts a study of subaperture fill factors, a subaperture design, and a discussion of issues which relate to the performance of phase retrieval algorithms.
