The fiber optical gyroscope (FOG) is an optoelectronic device that measures the angular velocity and the angle of rotation of the device that it’s fixed with. Its operating principle is based on the Sagnac effect. Russian and international companies are interested in the optical gyroscope for the prospects of its application as a rotation-sensing element in navigation, control and stabilization systems. In some cases, these devices can completely replace complex and expensive electromechanical (rotor) gyroscopes and three-axis gyro stabilized platforms. The fiver optical gyroscope can be made very compact in accordance with customer’s requirements. Among its other advantages is low power consumption, which is of importance when the device is used on board a moving object. The fiber optical gyroscope was developed in collaboration with Concern CSRI Elektropribor with financial support from the Ministry of Education and Science of the Russian Federation (project № 02.G25.31.0044).
