摘要：The present invention provides a signal processing method and device for thefiber-optic gyroscope, which can effectively expand the dynamic range of the fiber-optic
gyroscope, improve the linearity of the scaling factor, and restrain the zero drift of theopen-loop fiber-optic gyroscope, i.e., the dynamic fluctuation of the scaling factor. Thefiber-optic gyroscope proposed by the present invention provides a first harmonicdemodulation reference signal and a second harmonic demodulation reference signal,which are high in quality and synchronous in detection signal, to the signal processingdevice proposed by the present invention by the digital phase-locked loop technology.
