摘要
主要介绍了紫外气体放电灯、紫外LED、紫外激光器的工作原理及其优缺点，利用紫外LED阵列作为发光元件，研制了紫外调制光源，可产生不同调制速率和不同占空比的标准紫外调制信号，最终通过光纤输出，实现光功率的量值溯源。实验结果表明，紫外调制光源的光纤输出耦合效率约为8％，最高调制速率大于2MHz，满足目前紫外光通信接收机灵敏度的测试要求。
Working principle, advantages and disadvantages of laser are introduced. UV modulated light is developed using UV modulation signal with different modulation rates and different power, the modulated light is outputted by optical fiber. The ultraviolet （UV） discharge lamp, UV LED and UV LED as the original light, can produce standard UV duty ratios. In order to solve traceability of optical experimental results show that the modulated light meets the requirements of UV communication receiver sensitivity test, whose optical fiber output coupling efficiency of UV source modulation is about 8 %, and the maximum modulation rate is higher than 2 MHz.
