Abstract

A means and method of photonic heterodyning wherein at least one photonic beam set having fundamental frequencies to be heterodyned is used to produce a dynamic interference image that is projected onto an image component separator. Energy from selected portions of the dynamic image is separated into at least one output. Energy components within the dynamic image move relative to the separating locations as determined by the fundamental input frequencies. This causes intermodulation of the input signals and the development of energy at the sideband frequencies in the output(s). Special Interference is also used to provide amplified photonic heterodyning.
