The LS-FOG-02B Series Biaxial Optical Fiber Gyroscope is an inertial angular rate sensor based on optical Sagnac effect, which is used to measure the angular rate of the carrier orbiting around the sensitive axis of the gyroscope. The unit of angular rate sensing of the gyroscope is fiber loop. A close loop detection circuit is used to extract the fiber loop sensitive phase difference of light spread clockwise and counterclockwise and caused by external physical angular velocity. In the meantime, phase difference signal is translated into voltage signal for close loop feedback and control, realizing signal modulation and demodulation, so as to detect angular rate signal with high precision.

This product is composed of optical regular velocity sensitive unit and signal detection, providing information about biaxial angular rate. This product is mainly applicable to seeker, inertial navigation system, pilotless aircraft and robot posture monitoring system. Optical path unit: including SLD illuminant, fiber loop, integrated optical phase modulator, optical fiber coupler and photoelectric detector. Circuit unit: illuminant-driven circuit, detection and control signal circuit board; Gyro structural part.
