<title>Compact Coherent Light Valve Processor</title>

Abstract

The coherent light valve (CLV) processor is a video input signal processor which employs a CLV tube as a two-dimensional optical modulator . This CLV tube is a modified version of one used in a commercial General Electric TV Video Display Projector. CLV optical processors have been used for some time for wideband spectrum analysis and other specialized signal processing operations. They can provide large time-bandwidth processing with a 200 Hz or less spectral resolution over a 10 to 20 MHz bandwidth. Processor configurations range from the usual optical bench and optical table installations to electronic enclosures. Continued work has been directed to a system configuration more suited to the user environment. This paper discusses a current project development, termed the compact CLV Processor. In this configuration the processor is packaged to fit into a standard relay rack, almost the size of the present CLV projector unit. This configuration and extended versions will be described.
