ENERGY BEAM CONTROL, SIGNAL PROCESSING, AMPLIFICATION, AND COMPUTER LOGIC CIRCUIT USING INTERFERENCE EFFECT Russian patent published in 1999 - IPC

FIELD: optical processor units. SUBSTANCE: method involves producing specific interference of one first combination of beams with at least one second combination of beams in at least one third position. Energy is deflected from both combinations of beams to fourth position where energy from one of or any of beam combinations does not appear in absence of interference. Many devices using beam energy, including gated generators, gated amplifiers, phase demodulators, active filters, inverters, inverted filters and limiters, as well as AND, OR, EXCLUSIVE OR, NOT, NAND, and NOR gates, can be developed due to adequate selection of synchronization, levels, phases, frequencies, and interconnections of a lot of control devices. EFFECT: provision for effecting optical switching, optical calculations, control, and handling holographic and dynamic images. 66 cl, 36 dwg
