Resonant fiber-optic gyroscope signal processing system based on FPGA and ARM

The invention provides a resonant fiber-optic gyroscope signal processing system based on an FPGA and an ARM. The resonant fiber-optic gyroscope signal processing system comprises an A/D converter, an FPGA end, an ARM end, a D/A converter and a resonant fiber-optic gyroscope. The resonant optical fiber gyroscope comprises a tunable semiconductor laser, an optical isolator, an optical splitter, a first phase modulator, a second phase modulator, a first circulator, a second circulator, a coupler, an optical fiber annular resonant cavity, a first photoelectric detector and a second photoelectric detector. The signal input of the photoelectric detector of the gyro system is completed through the A/D converter; phase modulation signals and laser control signals are output through a D/A converter; the control of FPGA output signals, the sending of ARM end signals, the processing of gyro output data and the like are completed through an AXI bus protocol, a UART protocol and a TLV protocol.
