![عکس صفحه اول مقاله: Transmitting spectra-temperature characteristic of single-mode fiber coupler for fiber gyro application Transmitting spectra-temperature characteristic of single-mode fiber coupler for fiber gyro application](/preview/png/849936.png)
The relationship between the transmitting spectra characteristic of a fused single mode fiber coupler (SMFC) and the performance of interferometric fiber-optic gyroscope (IFOG) is analyzed in theory firstly. Then the transmitting spectra-temperature characteristic of SMFC is experimented, and the influence of the spectrum-stability of the SMFC on IFOG is simulated and experimented. Through the theory analysis and experiment research, it is confirmed that the spectrum output from the SMFC's throughput port is more stable than that output from the coupled port, and the bias instability of the rotation errors induced by the variation of spectrum output from the SMFC's coupled port is 10 times of that output from the throughput port. Therefore, to choose the SMFC's throughput port as the input port for navigation-grade gyroscope is an effective method to improve the IFOG's performance.
