Passive Standoff Super Resolution Imaging using Spatial-Spectral Multiplexing

Abstract

A summary of a new high-speed method of acquiring longitudinal spatial coherence functions is described within the context of imaging. The technique modulates incident spatial information onto spectral carrier frequencies, which can then be de-modulated in both amplitude and phase. An analysis of the technique's spatial and spectral resolution limits is also provided.
