PROCESSING OF OPTOELECTRONIC SYSTEM SIGNALS FOR MEASURING PARAMETERS OF DITHER VIBRATIONS IN A RING LASER GYRO

摘要

The report presents a functional diagram, main elements and the signal processing method of optoelectronic system for measuring dither vibrations parameters in a ring laser gyro. Operating principle of the system is based on registration of optical radiation reflected from areas of pattern with measuring marks. The proposed method of measuring system signal processing consists of noise filtering, signals offset and amplitude errors compensation, removing their waveforms distortion and phase shift, as well as using a tracking loop for evaluating the measured dither vibrations parameter.
