Mid-frequency controlled phase modulator for fiber optic gyros and fiber optic gyros

摘要

A fiber optic gyro control system (100) includes a phase modulator (110) for modulating a phase of a light signal (115) and a control unit (120) for generating a control signal (125) whose magnitude modulates the phase and that of the phase modulator (110) is supplied. The control signal changes statistically and is free of mean value.
