Paper Abstract

Described in this paper is fiber optic gyroscopes for harsh environment applications. The fiber optic gyroscope consists of a super luminescent diode, a fiber coupler, a polarizing optical fiber coil, a detector and a signal-processing device. The peak wavelength of SLD is 1.3 micrometer. 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 optic 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 aircraft inertial navigation systems and directional measuring system in oil-rigs.
