Patent ID: 7917039

Claim:
An optical signal processing system for data harvesting and pattern recognition on plural channels comprising: a mode locked laser for producing a comb of stabilized, coherent, phaselocked optical frequencies that are split into a first and a second identical optical frequency comb; a wavelength division demultiplexer to separate each individual optical frequency components of the first optical frequency comb to produce plural optical frequency components; a first modulator for modulating each one of the plural optical frequency components of the first optical frequency comb with a different one of plural target objects; a second modulator for modulating an input data signal with the second optical frequency comb; an optical splitter for splitting the modulated input data signal into plural optical frequency components each containing the input data signal; an optical combiner for simultaneously combining one of the plural optical frequency components containing a real time signal with one of the plural optical frequency components that contain one of the plural target objects to produce a temporally modulated interferogram; and a comparator for simultaneously comparing the plural optical frequency components containing the real time signal with the plural optical frequency components containing the plural target objects from the optical combiner on a comb by comb basis using balanced differential detection to determine if one or more of the plural target objects are found in the input signal, the system performing simultaneous matched filtering on plural channels.
