Abstract
A method for modulating a fiber optic gyroscope achieves a reduction in output noise beyond that possible through increased peak power with conventional phase modulation. A periodic modulation waveform is applied to an electro-optic modulator, such as an MIOC, to induce a periodic phase shift .phi..sub.M (t) where the form of the periodic phase shift is chosen such that the gyro random walk is below that associated with maximum output signal modulation.
