Frequency response of a laser gyroscope was studies by numerical modelling of a complete system of equations describing it. The calculation results are compared to the results of experimental measurements taken on a precision dynamic test bench. The frequency response was measured for a gyroscope based on a four-mirror ring laser with a non-planar contour, operating on He-Ne active mix at the wavelength of 632.8 nm. In the gyroscope under study, the sign-variable dither was implemented on the basis of Zeeman magnetooptical effect. The relationship between the measured and designed values of the frequency response distortions has been found. The relationship between the frequency response distortions in a laser gyroscope and inequality of field intensities of the counterpropagating waves (CPW) has been numerically calculated and confirmed by experiments. Based on the research results, the parameters of a ring laser can be optimized to improve the accuracy of measurements by means of laser gyroscopes.
