ABSTRACT:
A ring laser gyroscope having apparatus for compensating a gyroscope output signal for optical power variations in accordannce with variations of a dihedral frequency. A scaler quantity is determined based on operational data and it is used to compensate the gyroscope output signal. Alternatively, a gyroscope output signal is compensated via a feedback network by adjusting the gain medium in the laser gyroscope in accordance with variations in the dihedral frequency.
