Optical Heterodyne Fiber Gyro
Transactions of the Society of Instrument and Control Engineers
A phase-nulling detection is useful for obtaining a good linearity and scalefactor stabilization in a fiber gyro. We utilize optical heterodyne technique followed by a electronic phase-nulling detection, which provides electric signal frequency proportional to the rotation rate. To reduce the output drift, the optical system of the gyro has little pathlength difference and no frequency difference in the fiber loop between counterpropagating waves. Reduction of the output noise that is due todoi:10.9746/sicetr1965.19.319 fatcat:f3kiorhpszhs7glur6tswzofhq
