Abstract. Using the light modulator based on electrically controlled reflection in the interface between isotropic dielectric and nematic liquid crystal has been viewed. The optical scheme of a laser projection microscope (LPM) with a liquid crystal modulator (LCM) in treatment, observation and recording channels has been proposed, implemented and investigated. In the proposed scheme, LCM can act as a light beam splitter, attenuator and modulator simultaneously. Possibilities of some thin film materials processing by LPM with LCM in the treatment, observation and recording channels are demonstrated.
Keywords: liquid crystal, modulator, optical scheme, super radiant laser medium.
