摘　　要：由于突发包具有突发和大动态范围的特点,因此快速准确地检测突发光包的光功率是一个难点。文章简要介绍了光功率监控的基本原理,阐述了使用快速采样保持技术来实现突发光功率监控的方法。根据此方法设计了监控电路,并完成了配套的校准方法。实验结果表明,该方法监控精度高,动态范围大,能满足突发光功率监控的要求,且大大降低了对模数转换器的速率要求。As burst optical packets have the feature of bursting and large dynamic scope, fast and accurate detection of their op- tical power is difficult. This paper briefly introduces the basic principle of optical power monitoring and describes the use of the use the {ast sampling and holding technology method {or its implementation. Furthermore, it uses this method to design a mo- nitoring circuit and accomplishes the relevant calibration method. The experimental results show that with high accuracy and large dynamic scope this method meets the requirements for the burst optical power monitoring and greatly lower the speed re- quirement for A/D convertors.
