【摘要】 分析了超辐射发光二极管(Super Luminescent Diode,SLD)光源的驱动原理,给出了一种利用反馈稳恒驱动电流和功率,利用 ADN8830控制温度的方法来稳定光源的驱动电路,并通过采集反馈电压来监控电流、功率的输出。通过对 SLD 光源的驱动实验,得到电流及功率的稳恒控制,电流长期稳定度达到66ppm。更多还原

【Abstract】 This paper has introduced driving principle of SLD source.Driving circuit which canstabilize output current and power is given by feedback circuit,and using ADN8830 to control temperature.Then current and power are displayed by feedback voltage.Through the experiments of driven SLD,the better stabilization of this driving circuit is gained.The long term stability of output power is 66ppm.更多还原
