Abstract
Described in this paper are technical ways to improve the temperature stability of fiber optic gyroscopes. The fiber optic gyroscope consists of a super luminescent diode, an integrated optical circuit, a fiber coupler, a polarizing optical fiber coil, a detector and a signal-processing device. The peak wavelength of SLD is 1.3 micrometers . The multifunctional integrated optical circuit that includes a polarizater, a Y type junction coupler and a phase modulator, is manufactured with annealed proton exchange process. The polarizing optical fiber coil is fabricated by applying quadrupolar winding technology. The fiber optic gyroscope can work in high/low temperature, large acceleration, vibration, shock and other harsh environments. It is applied in strapdown inertial navigation systems, directional measuring system in oil-rigs and automobile positioning and guidance.
