AB - An optical system was constructed and tested that reads data in word parallel form from a selected address in an optical random access memory (RAM), and passes it to selected addresses in another RAM. The advantage of using optical random access memory is that software developed for a sequential electronic machine is easily transferred to this optically enhanced machine because the same instruction set may be used. In early optical computers, this advantage may outweigh not using optics to its full parallelism potential. An bit-slice search technique is used to generate a beam whose level is dependent on an optical address selected. Bit-slice units are used to select the read and write addresses. The system moves the data from a selected address on one storage device to one or more selected addresses on another. An optical experiment, using optically addressable liquid crystal light valves, image intensifiers, and spatial light rebroadcasters (SLRs), shows how a row of data may be selected optically for reading and then fanned out to more than one location specified by separate optical addresses.
