Abstract
An optical data processing system employing a programmable optical data processor for processing an optical data beam comprising a plurality of zero, one and two-dimensional modulators for spatially modulating the optical data beam, the modulators being interconnected such that lenses are not necessary to accomplish the focusless transfer of the optical data beam between the modulators. The plurality of modulators are controlled so as to permit the programmable processing of the optical data beam. The optical data processor realized is physically solid and compact and is readily capable of performing a wide variety of optical computations.
