Holographic Location of Distant Points (PREPRINT)
Abstract
Imaging is the obvious way to find out about what a scene contains if we have little or no a priori information about what the scene contains. But that changes if we have a priori knowledge of things imaging would provide. There is inherent redundancy if we measure what we already know. For instance, if we know that the object is comprised of one or more isolated distant point sources, we need not form an image to locate those points. Imaging is costly in many respects and the nonimaging systems have significant advantages. This paper shows how to use holograms to construct a flat, solid, small, accurate, small nonimaging point location system.
