Testbed for Precision Characterization of Spatial Light Modulators and Optical Processors.

Abstract

The purpose of this award is to construct a dedicated testbed for the characterization of phase and amplitude modulating properties of spatial light modulators (SLM). The system is specifically a phase shift interferometer configured around a 2000 x 2000 CCD imager to precisely measure the SLM transmittance and diffraction pattern with a resolution in excess of current SLMs. The testbed will be used in current and pending studies. It also bas application to a new optical correlation architecture described in a recent patent and journal paper.
