Abstract

We will review recent developments in coded aperture techniques for unconventional imaging systems. Specifically, we are interested in looking simultaneously in multiple directions using a common aperture. To accomplish this, we interleave several sparse sub-apertures that are pointed in different directions. The goal is to optimize the sub-apertures so that the point spread function (PSF) is well behaved, and resolution is preserved in the images. We will present an analysis of the underlying PSF design concept, as well as the necessary phase optimization techniques.
