Paper Abstract

This report describes closed-loop fiber optic gyroscope and related components for aircraft strap-down inertial navigation system. The closed-loop fiber optic gyroscope consists of super luminescent diode with working wavelength 1.3micrometers , fiber coupler, polarizing optical fiber coil which was fabricated by similar rectangle polarizing optical fiber with length of 500m by applying four grades symmetry twining round technology, photoelectric detector, and an integrated optical circuit (IOC) phase modulator fabricated with annealed proton and signal processing circuit technology.
