ABSTRACT:
An optical memory which allows for the high-speed random access of two-dimensional information. Portions of a light receiver made from material with photovoltaic or photoconductive effect are connected to corresponding portions of a ferroelectric liquid crystal panel through an amplifier layer. To write, a light image is shown on the light receiver. When light striking each portion of the light receiver is sufficiently strong, the state of the corresponding part of the liquid crystal panel is changed. The state of the panel can be read with an image scanner for scanning the liquid crystal panel.
