Digital Signal Processing for Open-Loop Fiber-Optic Gyroscope

Abstract:

Digital open-loop fiber-optic gyroscope detection scheme based on sinusoidal phase modulation is introduced. A novel implementation of the detection scheme is developed with digital signal processor (DSP) and field programmable gate array (FPGA). The design and implementation of the detection system are discussed. Timing control and open-loop signal preprocessing are realized in FPGA. Rotation rate calculation is finished in DSP. Experiments result shows that good performances have been achieved and the implementation scheme is of great practical value.
