This paper relates the development situation of FOG in China. New weapon system needs high performance Fiber Optic Gyroscope. Through analyzing basic scheme of FOG at home and abroad, comparing Technical index of ASE light source and SLD light source. Therefore, we suggest the Scheme of the high performance Fiber Optic Gyroscope based on SLD light source. Here discussed the Polarization Crosstalk,...
Y wave-guide is an essential component in the close-loop interference fiber optic gyroscope (IFOG) system. The application of Y wave-guide in IFOG enables FOG to have high scale factor linearity and has significantly improved scale factor stability and repeatability. The main function of Y wave-guide is polarizing, coupling and modulating the phase. Phase modulated includes double hands in IFOG. On...
With the spectral hole-burning effect resulting from coherent population oscillation in the homogeneously broadened material, the ultraslow light propagation phenomenon is used at room temperature in a fiber. One-dimensional wave equation for envelopes light propagation is derived. We present an electronic circuit which simulates wave propagation in dispersive media. Fiber optic gyroscope which improves...
Based on the digital phase ramp feedback technique and advanced digital signal processing techniques, the digital detection system for closed-loop FOG is developed with digital signal processor (DSP) and field programmable gate array (FPGA). The dynamic model and the simplified linear discrete model of the detection system are established. Digital control algorithm in the closed-loop control is analyzed,...
