ABSTRACT:
A plurality of reflective diffusing holographic memory elements (16) is positioned on a memory plate (14). An array (24) of detectors (22) faces at least one of the memory elements. A laser (26) illuminates the selected memory element and the data stored therein is reflected onto the array for reading. A new memory element may be illuminated or may be brought into interrogation position.
