Abstract:

Three sampling circuits, a subtraction circuit, and a divider circuit cooperate to sample an output signal from a nonlinear interferometric sensor at proper times, to subtract output signal samples to obtain a difference signal, and to divide an output signal sample into the difference signal to remove noise-induced modulation from the output signal.
