Readout signals of a dithered ring laser angular sensor are processed by a signal combining circuit which forms part of a closed-loop dither signal remover scheme. The output of the signal combining circuit is demodulated as a function of the dither applied to the ring laser sensor and subsequently utilized to control a correction signal. The signal combining circuit combines the readout signal and the correction signal to yield an output signal stripped of substantially any dither signal components.

Dither signal remover for a dithered ring laser angular rate sensor

Disclosed is a readout apparatus for obtaining single beam and double beam signals for a ring laser angular rate sensor.

Readout for a ring laser

A discriminant apparatus for laser angular rate sensors which provides an output signal related to a selected weighted vectorial sum of the coupling of energy between counterpropagating waves traveling about a closed-loop path. The discriminant apparatus is utilized in a closed-loop control system for minimizing the lock-in rate of the sensor and/or maintaining and selecting scale factor linearity.
