IMAGE GENERATING SYSTEM

摘要

A display system (400) for acting on light entering the system includes a reflective ferroelectric liquid crystal spatial light modulator (402) and a polarizer arrangement. The polarizer arrangement includes a polarizer (405) for polarizing the light entering the system and directing the polarized light into the spatial light modulator (SLM) along an optical path having an optical path axis, an analyser (406) configured to receive and analyze the optical output of the SLM (402) and to direct the analyzed optical output out of the system, a compensator (404) between the polarizer (405) and the SLM (402) and in the optical path between the SLM (402) and the analyzer (406) and a passive wave plate (408) in the optical path between the light source (410) and the SLM and in the optical path between the SLM and the viewing area. The compensator includes a layer of ferroelectric liquid crystal light modulating medium switchable between a first compensator state and a second compensator state.
