摘要
根据三轴一体化光纤陀螺共享光源,要求光源能够提供较大的高精度的恒流以满足实际需要。结合SLD（超辐射发光二极管）光源结构特点及其工作原理,采用恒流和温控方案,设计了新的高精度恒流驱动和温度控制系统。经测试结果表明,设计的系统能够在环境温度为-45℃-70℃内稳定工作,实现了高精度恒流和温度驱动控制,满足三轴一体化光纤陀螺对光源驱动的要求。
In order to satisfy the reality need, the larger and higher current source is required to share the same light source with the three-axis integrative fiber optic gyroscopes. Based on the characteristics of structure and the operation principle of the SLD light source, a new current source and temperature control system are designed by adopting a scheme of current source and temperature control. Experimental results indicate that the system can stably work between -45℃ to 70℃ , realize higher current source and temperature control and satisfy the requirement of three-axis integratire fiber optic gyroscopes to light source.
