| 英文摘要: |
| Based on the characteristics of assembly of fiber optic gyro using discrete optical device, we discuss the influence on the accuracy of fiber optic gyro in the aspects of fiber type matching, loss matching, and polarization matching. We give ideal matching parameters of the device of fiber optic gyro and the optimization of shaft precision when polarization pigtail is connected. It increases the consistency of the fiber optic gyro production, and ensures batch stability, reproducibility and the performance of fiber optic gyroscope. |
