摘　　要：光纤陀螺(FOG)所用光源的特性对光纤陀螺的性能有很大的影响,着重介绍半导体光源超辐射二极管(SLD)的特性,以及SLD的稳定性对光纤陀螺的影响。针对环境温度和驱动电流对SLD光功率稳定性的影响,设计光功率控制方案及相应的驱动控制电路。The light source used in the fiber-optic gyro (FOG) has great effect on the performance of FOG. In this article,we pay great attention on the character of the superluminescent diode(SLD) and analyze the effect of SLD′s stability on FOG. With the effect of environmental temperature and driving current on the stability of SLD′s light power, we design the control schema of light power and SLD′s driving circuit diagram.
