Acousto-optic digital computer fundamentals

The author describes how programmable, arbitrary-bit-length, all-digital central processing unit (CPU) computations are now possible by using control logic to compute ALU (arithmetic and logic unit) primitives for emulating a general-purpose programmable computer. These primitives are then executed sequentially in order to calculate 32-b or larger primitives. The author initially discusses the theoretical background which addresses Shannon´s expansion theorem (1938), Morozov´s control operator method (1984), and DeMorgan´s laws. These three schemes are then coupled and mapped onto current optical computer hardware technology using laser diode arrays, multichannel acoustooptic spatial light modulators, and avalanche photodiode arrays
