Interference type fiber optic gyroscope working principle and structure
Dec 13, 2018

At present, there are three main types of fiber optic gyro according to the working principle: interferometric fiber optic gyroscope (IFOG), resonant fiber optic gyroscope (RFOG) and Brillouin fiber optic gyroscope (BFOG). Among them, the research on resonant fiber optic gyroscope and Brillouin fiber optic gyroscope is still not mature, and it is still in the stage of laboratory verification and basic theory research, while the interferometric fiber optic gyroscope is the most mature and widely used fiber optic gyroscope. instrument. Medium- and low-precision interferometric fiber optic gyroscopes have been commercialized in mass production and have been used in many fields. This paper focuses on the working principle and structure of the interferometric fiber optic gyroscope.
