Abstract
An optical phase modulating method of a multi-integrated optical circuit of an interferometric fiberoptic gyroscope with a control feedback control with a digital modulation and demodulations approach includes the step of modulating at eight modulation levels. Each modulation levels has a duration of one-quarter of a light propagation time in a fiberoptic coil.
