Dithered laser angular rate sensor.

摘要

@ Readout signals (13) of a dithered ring laser angular sensor (10) are processed by a signal combining circuit (100) which forms part of a closed-loop dither signal remover scheme. The output of the signal combining circuit is demodulated (110) as a function of the dither applied to the ring laser sensor and subsequently utilized to control a correction signal (130). The signal combining circuit combines the readout signal and the correction signal to yield an output signal stripped of substantially any dither signal components.
