Abstract
A means, method and apparatus for dual-phase amplification of wave-type signals is disclosed comprising superimposing a constant level beam set and a modulated beam set to produce a first interference image at first and second locations. A first image component separator separates energy from constructive and destructive interference component regions to produce secondary beam sets that are combined to produce a second interference image, which is separated at a destructive interference region to produce the output. The amplifier with multiple inputs is then connected in cascade, as a phase-bistable device, as a level detector, an AND, an OR, and/or a synchronized oscillator. Multiple frequencies work independently, allowing for frequency-multiplexed functions.
