Abstract
A kind of infrared Liquid Crystal Light Valve (IRLCLV) based on polymer/liquid crystal is introduced to improve IRLCLV's response. The structure, technical process and conversion characteristics in visible-infrared image system were studied. The IRLCLV shows fast response and weak dependency with thickness. Also the device has simple fabricating process and high reliability. In visible-infrared image system, 100Hz frame rate and 10lp/mm spatial resolution were measured. It will provide wide dynamic range and high frame rate IR scenes for optic-electro simulation and testing systems.
