A simple analogue phase tracking circuit for the fibre gyroscope is described. The system provides a linear output from an open loop gyroscope configuration over a range in Sagnac phase shift >±500° Sagnac, with good linearity and relatively low noise and drift. The use of this demodulator in low-cost medium grade fibre gyroscope applications is projected.
