ABSTRACT:
A method for accurately converting to an electrical signal a modulated optical signal, the modulation frequency of which randomly varies in a narrow range about a predefined optimum modulation frequency, includes the steps of receiving the optical signal at an optical detector, producing as an output of the optical detector an electrical signal corresponding to the optical signal, the amplitude of which electrical signal varies with frequency, and modifying the amplitude of the electrical signal, depending on the frequency of the electrical signal, inversely to the variation of the amplitude of the electrical signal with frequency caused by the optical detector.
