PROM-THEORY AND APPLICATIONS FOR POCKELS READOUT OPTICAL MODULATOR

Theoretical analyses and experimental characterizations of the Itek PROM (Pockels Readout Optical Modulator) are reviewed. The basic operational principles are discussed, followed by a theoretical description of the dependence of PROM characteristics on fabrication and operational parameters. Results of various characterization programs are presented. Of particular interest are resolution and diffraction efficiency experiments. A discussion of PROM fabrication techniques, materials, and design, both present and future, is included. Examples of some applications for which the PROM may be used are given. Applications include: incoherent image enhancement, image or signal correlation, real-time spatial filter generation, and two-dimensional logical operations.
