ABSTRACT:
A method and apparatus for correction of laser gyro dither pickoff signals. Dither pickoff signals are sampled during the dither input signal cycle at points where error is more prevalent in the dither pickoff signal. The samples are then used to modify correction factors used in the calculation of a corrected dither pickoff signal.
