Abstract:

Subject of study. Methods to reduce the error of fiber-optic gyroscope with birefringence modulator during temperature changes. Aim of study. Development and experimental testing of a way to compensate the nonlinear impact of temperature on the error of a fiber-optic gyroscope with a birefringence modulator. Method. A method is proposed to reduce the temperature influence on the fiber optic gyroscope error by increasing the optical fiber length to values exceeding the depolarization length, which allows for reducing amplitude modulation of a signal caused by parasitic interference effects. Experimental studies were conducted on the influence of temperature changes and the rate of these changes on the fiber optic gyroscope error. Main results. The root mean square deviation of the signal decreased from 0.055 to 0.023 deg/hour within the temperature range of 16 to 36 °C and from 0.01 to 0.003 deg/hour under stable temperature conditions. Additionally, the signal drift decreased from 0.33 to 0.13 deg/hour in the specified temperature range and from 0.055 to 0.019 deg/hour under stable temperature conditions. Nonlinear segments in the angular velocity signals' dependence on temperature were eliminated. An additional time delay between wave trains with orthogonal polarization states is created to reduce the error of a fiber-optic gyroscope with a birefringence modulator. Practical significance. The method offers a means reduce the influence of temperature on the accuracy parameters of navigation systems.
