The use of a multimode (compact-disk type) laser diode in a dual Michelson interferometer arrangement is investigated, both theoretically and experimentally, by using the technique of coherence length modulation. A reproducible way of shifting the interference regions is considered for the potential use of the technique in optical sensors, for flow or distance measurement.
