Abstract


There are many advantages with Fiber Optical Gyro such as small in size, simplestructure, less component, low cost, impact resistance, resistance to acceleration motion,wide dynamic range and good in electromagnetic compatibility, and the performance ofFOG could be excellent in theory. But in fact it’s very difficult to achieve that with highperformance and low cost because of various interference factors and error. This paperreference the gap of development level between domestic and abroad in FOG putforward based on improving domestic manufacturing quality level optical device at thesame time, the influence of fiber optic gyroscope precision of the various error sourcesare analyzed, and according to the characteristics of optical elements of fiber-opticgyroscope system optimization point of view.Firstly, this paper lists the influence of fiber optic gyroscope accuracy factors baseon the analysis of the working principle of the optical fiber gyroes, and kinds of theerror sources influence put forward some solutions.On this basis, the paper from the vibration of fiber optic gyroscope mechanism ofthe finite element modeling simulation method, the optical fiber gyro fiber optic ring thevibration characteristics, this paper analyzed by vibration suppression and reduce errorsmeasures.Next on the theoretical analysis of the temperature change the influence of fiberoptic ring precision, and the comparison of the fiber optic ring around the methods indifferent temperature drift on the inhibition of size, with four very symmetrical inaround the method of fiber optic ring around the system to the defects improvingmeasures are put forward, and the main optical components of the experimenttemperature, temperature compensation for provides parameters basis.Final paper of fiber-optic gyroscope circuit parts, through to the circuit parametersis analyzed and calculated, and determine the main components of the performanceindex selection, realized the small amplification, noise filtering, feedback output circuitdesign requirements.
