Imaging Characteristics of the Itek PROM

Abstract

This paper discusses advances in the fabrication, operation, and performance of the Itek PROM (Pockels readout optical modulator). Devices of high optical quality have been made and evaluated. Measurements of MTF and sensitivity under various conditions are presented. Stored images can be enhanced in contrast by a change in device voltage and the same method used to suppress the zero order in Fraunhofer diffraction patterns of such images. The results of this technique are demonstrated.
