ABSTRACT:
A digital synthetic serrodyne phase difference controller for a rotation sensor capable of sensing rotation about an axis of an optical fiber coil based on having a pair of electromagnetic waves propagating through the optical fiber in opposite directions to both impinge on a photodetector with a phase difference relationship therebetween, the digital synthetic serrodyne phase difference controller including a positive serrodyne generator and a negative serrodyne generator having outputs which input to a common adder. The bit output of the adder is converted to analog in a digital-to-analog converter and applied to operate a frequency translating device in the optical path with the coil.
