1. A method for converting to an electrical signal a modulated optical signal subject to variation about a predefined modulation frequency, comprising the steps of:

  • (a) receiving the optical signal at an optical detector;

    (b) producing as an output of said detector an electrical signal corresponding to said optical signal, the amplitude of said electrical signal varying with its frequency;

    (c) adjusting the amplitude of said electrical signal in a predefined frequency-dependent manner, inversely to the variation of the amplitude of said electrical signal with frequency of said step (b).
