Abstract

We present an optically addressed liquid crystal light valve based on a twisted nematic liquid crystal layer associated to a photoconductive BSO layer. Based on the optical addressing of a continuous layer of liquid crystal, the spatial transmittance distribution of 1053nm coherent light through the light valve has a corresponding relationship with the intensity distribution of 470nm incoherent light projected onto the photoconductive BSO layer. This relationship has been studied experimently. As a transmissive device, it has the advantage of high transmittance and it can overcome the problem of black-matrix effect. The aperture of our device has reached 22mm× 22mm.
