数字闪变仪，基于IEC模拟闪变仪而来，通过低通、高通滤波器、视感度加权滤波、平滑滤波后得到瞬时闪变视感度值。-Digital flicker meter, based on the IEC flicker meter analog, low pass, high pass filter, depending on the sensitivity weighted filtering, smoothing the instantaneous flicker sensation value.

前后向平滑算法：算法的原理很简单，以五点三次平滑为例。取相邻的5个数据点，可以拟合出一条3次曲线来，然后用3次曲线上相应的位置的数据值作为滤波后结果。简单的说就是 Savitzky-Golay 滤波器 。只不过Savitzky-Golay 滤波器并不特殊考虑边界的几个数据点，而这个算法还特意把边上的几个点的数据拟合结果给推导了出来。-Before and after the smoothing algorithm: the principle of the algorithm is very s
