The image on an optically addressed spatial light modulator, also known as a light valve, is created and changed by shining light encoded with an image on its front or back surface. A photosensor allows the OASLM to sense the brightness of each pixel and replicate the image using liquid crystals. As long as the OASLM is powered, the image is retained even after the light is extinguished. An electrical signal is used to clear the whole OASLM at once. Webbasic principle of operation of an optically addressed light valve is the following. A photosensitive layer detects the incident intensity distribution and induces a charge distribution onto a material which modifies its optical properties as a function of the photo- induced voltage.
