摘　　要：提出了一种快速有效的实时光功率监测数据处理方法,它利用加权平均法抑制光功率采样数据的跳变。不同时期的光功率采样数据的权数不同,当前的采样数据权数为1/2,第一次的采样数据权数为1/2n-1。对所有的采样数据进行加权平均得到的加权平均值即作为实时的光功率数据。本方法比简单累次算术平均处理方法速度更快,对光功率采样数据跳变的抑制效果也非常明显。In this paper, a fast and effective data processing method of real-time optical power monitoring is put forward. Weighted average method is used to restrain the jumpiness of sampled optical power data. Sampled optical power data have different sample time, so they have different weight factors. The weight factor of the current datum is 1/2 and the weight factor of the first one is 1/2^n-1. The real-time optical power datum is the weighted average of all of the sampled optical power data. The processing speed of this weighted average method is faster than that of the simple arithmetical average method and the effect of restraining the jumpiness of the sampled optical power data is obvious.
