Approximation of Reproduced Dependences of Scale Factor and Orientation Matrix of Measuring Axes of a Three-Axis Quasi-Four-Frequency Zeeman Laser Gyro

Dependences of scale factor and orientation matrix of measuring axes of three-axis quasi-four-frequency Zeeman laser gyro upon the angular speed of rotation are considered. It is found that the temperature dependence of the scale factor is determined by change in the gain loop width of the laser фсешму medium and by the resonator s linear extension, which is well approximated with a linear function. Similarly, the change in orientation of measuring axes of a laser gyro, which is determined by the elastic thermal restraints, can be described. At the same time the dependence of the scale factor on the angular speed of rotation is determined by the static area of capture and by change in losses in the resonator (frequency offset) during the transfer from one generation mode to another and by variation in temperature.
