ABSTRACT:
An optical fiber rotation sensor having an ordinary single mode fiber coil with a depolarizer in series therewith configured with component optical path lengths therein and birefringent axes relationships therein chosen with respect to the source autocorrelation. Amplitude related phase errors due to polarization mode coupling can be eliminated or reduced economically, and signal fading can be substantially prevented.
