摘要
The environmental noise in interferometric fiber optic gyroscopes (IFOGs) has a significant impact on the self-noise and angle random walk (ARW) at 0-100Hz, the bandwidth commonly used in applications. The stability of the structure affects mostly bandwidths larger than 10Hz, while the airflow in the environment mainly affects that lower than 20Hz. The self-noise in a well-fixed structure and a nonwind room is experimentally demonstrated as 1.3441x10(-8)rad/s/root Hz and 2.3896 x10(-8) rad/s/root Hz, 9.08dB and 9.23dB lower than that with environmental noise, respectively, at 100Hz in the 9-km IFOG. This proves that it is essential to avoid environmental noise for the use and testing of high-precision IFOGs.
