Abstract

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.
