Abstract

An appealing approach to implementing spinning reticle trackers in the pupil plane is presented. The advent of research in spatial light modulators and addressable mirror arrays may allow achievement of pupil plane processing in the next few years. Reticles were generated with the general FM reticle equation, and FFTs of the reticles were obtained. Magnitude and phase plots of these reticles are shown. The magnitude plots are easily understood; however, the phase plots will take more study before implementation is tractable.
