Abstract
An analysis is made of a processor for compression of optical signals with linear wavelength modulation. The processor system is equivalent to a diffraction spectrometer except that a linear charge-coupled photodetector operating in a delay-and-add mode is inserted in its spectral plane. By this means the processor isolates the signal from the noise and is invariant to the signal arrival time, and it can be tuned by a simple electronic technique to select signals with a different rate of change in wavelength. The compression coefficient may be several thousand. Other characteristics of the processor and its maximum capabilities are discussed.
