A review of the methods of obtaining and processing the VOG signal is carried out. A gyroscope with the formation of a phase information signal in an interference loop (at the optical level) is proposed. The analysis of digital phase difference meters is carried out. The advantages of a gyroscope with a phase information signal and digital signal processing are the linearity of the scale factor, an increase in the dynamic range and a reduction in the influence of external factors on the measurement result.
