The present spatial light modulator employs an amorphous silicon photoconductor and a nematic liquid crystal to yield 501 p/mm MTF. The resolution is found to be improved by thinning the photoconductor and liquid crystal, as well as through the optimization of the device''s driving condition. Device response is limited by liquid crystal response; it is anticipated that faster response will be possible through the use of a ferroelectric liquid crystal.
