Liquid Crystal on Silicon Infrared Scene Projectors

As the deployment of IR sensors increases in the military arena, so does the need for testing, calibration and training in realistic infrared environments. This paper introduces liquid crystal on silicon (LCOS) technology and discusses key elements required to successfully transition these displays to the infrared. The resulting devices are not only appropriate for infrared scene projectors, but can also be used as infrared adaptive optics or non-mechanical beamsteering elements.
