Study of high performance Fiber Optic Gyroscope based on SLD light source

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-Spectra and Loss etc of optical path, Error of high performance Fiber Optic Gyroscope caused by all the above parameters. A high performance FOG prototype existing conditions was designed, Higher performance need to keep on improving.
