ABSTRACT:
An error reducer for reducing rotation rate errors arising because of an optical Kerr effect occurring in a coiled optical fiber in a rotation sensor. Through amplitude modulating electromagnetic waves propagating in that coil. A signal obtained from the coil based on the amplitude modulation component therein is used in a feedback loop to reduce or eliminate such errors.
