1 February 1992 Single-channel phase-tracker for the open-loop fiber optic gyroscope
Author Affiliations +
The present, simplified analog signal-processing technique for an open-loop FOG is based on Kersey and Moeller's (1990) closed-loop phase-shift-nulling concept. This approach emulates the operation of a true closed-loop gyroscope on the basis of low-cost phase tracking, and furnishes a linear output from an open-loop gyro configuration over a +/- 2-pi radian range in Sagnac phase shift. Good linearity and comparatively low noise and drift characteristics are obtained.
