| Abstract: | Effect of spike pluses in PIN-FET output signal on bias drift of fiber optic gyro is analyzed for the first
time in this paper. The error model of bias drift resulted from spike pluses is given. After the character of PIN-FET output
signal of fiber optic gyro is analyzed, a time-domain input signal strobe method based on high-speed analog switch is
designed for elimination of spike pluses in PIN-FET output signal. Finally, an experiment is made to verify the error
model, the experimental results show that the theoretic analysis and the designed spike pluses suppress method is practicable
and the bias drift resulted from spike pluses can be decreased effectively. |
