Visible-to-infrared dynamic image-converting system with a liquid crystal light valve

摘要

A kind of liquid crystal light valve (LCLV) based on a CdS-CdSe photoconductor that can convert visible image to infrared at video rate is introduced in this paper. A prototype of a visible to infrared dynamic image converting system using a CO$-2$/ laser as the infrared source is built with this device. Results of the converter are presented in this paper.
