ABSTRACT:
A ring laser gyroscope has noise reduction means which removes or compensates for errors which result when a bias or dither is imparted to the gyroscope in order to reduce or avoid lock-in. In one embodiment the gyroscope has processing means (25) including two photodiodes (26,27) which are exposed to the fringe pattern of the gyroscope output beams and which, by the use of a Norton input operational amplifier (30) configured as an electronic integrator, produce a signal which is algebraically summed with the uncorrected gyroscope output signal to produce a corrected gyroscope output signal.
