单光纤光纤陀螺采用的是单光纤在线制作技术。由于这种方法是把所有的光器件都放在一根光纤上制作,因此各光器件的连接处没有融接点,并且光器件的性能可在线控制。在分析其结构的基础上建立了开环FOG的光学模型,并进行了误差分析。指出了单光纤光纤陀螺方案是低成本、高可靠性、易于工程化的一种方案。
Single-fiber FOG uses a single fiber online production technology. Since this method puts all optical components on one optical fiber, there is no fusion point at the junction of the optical components, and the performance of the optical components can be controlled online. Based on the analysis of its structure, an optical model of open-loop FOG was established and the error analysis was carried out. It is pointed out that the single-fiber FOG solution is a low-cost, high-reliability and easy-to-engineer solution.
