All-birefringent-fiber frequency-modulated continuous-wave Sagnac gyroscope
Author(s): Jesse Zheng

Paper Abstract

An all-birefringent-fiber frequency-modulated continuous-wave (FMCW) Sagnac gyroscope is described. The rotation velocity of the gyroscope is determined by measuring the phase shift of the beat signal produced by the two counter-propagating laser beams in the birefringent fiber coil. A resolution of 0.02 deg/sec with a 100-m fiber coil has been observed.
