Paper Abstract

Liquid crystal spatial light modulators are emerging as a potential replacement to traditional optical beam steering methods. The performance of these devices for optical communication systems in the radiation environment for geostationary orbits (GEO) are of interest for applications in the next generation of satellites. As an initial investigation to the study presented, several liquid crystals were irradiated to total dose levels consistent with expected GEO environments. While prior irradiation work has been done on spatial light modulators none is known to include a first look at a liquid crystal and CMOS backplane. Parameters of retardation, contrast ratio and primary power current were monitored at incremental stages during the test and are presented.
