Abstract
The apparatus and method of the present invention employ solid state dynamic diffractive optical elements for reading information from a diffractive optics memory. The diffractive optics memory has stored therein information located at a plurality of points of the memory and at a plurality of angles at each one of the points so as to form a plurality of packets of information at each of the points. A matrix of the dynamic diffractive optical elements is configured to shape a laser beam to address the memory at one of the angles of one of the points to reconstruct one of the packets of information.
