ABSTRACT:
A phase difference controller for a rotation sensor based on a coiled optical fiber operating a dual output generator and signal combiner to provide a composite signal to operate a frequency translating device in the optical path with the coil. The combined signal of appropriate frequency and polarity operates the translating device to provide a phase difference shift in the optical path.
