Modeling of Scale Factor Nonlinear Distortions of Laser Gyro with Alternating Rectangular Bias
The results of scale factor nonlinear distortion measurements related to the light backscattering effect in a laser gyro with a alternating rectangular bias are presented. It is shown that analytical relationships taking into account the conservative and dissipative backscattering components adequately describe a laser gyro frequency response in a wide working range of angular rotation velocities. The use of these relationships should reduce the values of nonlinear distortions down to 1–2 ppm by a proper scale factor correction.
