摘要：
In a liquid crystal light-valve with optical feedback we show that localized structures can be stored as elementary pixels lying on matrices that are impressed in a small pretilt angle of the nematics contained in the valve. The molecular reorientation, which is induced by the optical feedback, is bistable and may be controlled by a suitable phase profile superimposed on the input beam.
