光纤陀螺用超辐射发光二极管启动模型研究

为了实现光纤陀螺的快启动, 从超辐射发光二极管(SLD)发光机理出发, 通过分析光源的驱动电流和管芯温度在上电后的变化规律, 建立了SLD的启动模型, 找出了影响SLD启动时间的因素。用高速数据采集卡测得SLD的常温启动时间约为3~4 s, 由温控系统系统引起的功率波动误差为4.5%, 波长的漂移量为0.92 nm。实验测试结果与建立的理论模型相符,从理论上提出了缩短SLD启动时间和实现陀螺快启动的方法。

Abstract

In order to realize the quick start-up of fiber optic gyroscope, the start-up model of the superluminescent light emitting diodes (SLD) was established by analyzing the change principle of drive current and temperature in SLD after power on, and the factors affecting the start-up time of SLD were got. By using high-speed data acquisition card, the start-up time of SLD was measured to be 3-4 s at room temperature, the power fluctuation error was 4.5%, and the wavelength drift was 0.92 nm caused by the temperature control system. The experiment results were consistent with the theoretical model established. The methods to reduce the start-up time of SLD and realize the quick start-up of fiber optic gyroscope were proposed in theoretically.
