Abstract

The paper describes an interferometric fiber-optic gyroscope (IFOG) of a new configuration, i.e., with a birefringence modulator (IFOG-BRM) is proposed. According to the proposed scheme, a prototype model of the device has been assembled and tested to estimate its drift on a stationary base. Dependence of the IFOG-BRM drift on the temperature has been determined. According to the test results, the error of angular rate estimation is 0.05 deg/h; however, high sensitivity of the device to the absolute temperature variations has been revealed.
