| 中文摘要 | 介绍了谐振型和干涉型两种微光学陀螺仪的分辨率计算公式,并在光纤仿真装置上,分别进行了系统结构的实验研究。在谐振型装置中,作为光源采用了具有Bragg光栅的窄线宽激光二极管。在干涉型装置中,为了保证双向光束在Sagnac效应敏感环(SSR)中可以循环传播,采用了大功率的超辐射发光二极管(SLD)作为光源。为了保持双向光束在SSR中循环传播多圈,需要在SSR中插入一个光放大器,以补偿光束在传播中的各种损耗。研究结果表明,所建议的系统结构对于开发中等精度的微光学陀螺仪产品具有可行性。; Both resonant and interferential system configurations for developing micro optical gyro (MOG) were investigated with calculating their resolution and experimenting on their fiber analog setups. In the resonant setup, the narrow line width laser diode with Bragg grid was used as the light source. In the interferential setup, the high-power light source of super luminescent diode (SLD) was used to ensure bi-directional light beams in Sagnac sensing ring (SSR) to circulate for several round trips. In order to keep the light beams circulating in SSR for many round trips, it is necessary to insert a semiconductor optical amplifier in the SSR for compensating the propagation losses of light beams. The results of investigation verify the feasibility of the proposed system configuration for developing MOG with moderate accuracy. |
