Since the measurement initiation is controlled by the leading slope of the pulse, part of the pulse is lost and the resulting spectrum is distorted unless some pretrigger delay is specified.
因为测量的引发是由脉冲的前导沿控制的，除非设置一定的预触发延迟，否则会丢失部分脉冲、造成频谱失真。

By means of the improved setup, the slope and curvature measurement of out-plane deformation is realized.
利用这一改进光路实现了离面变形的斜率和曲率测量。

So, it becomes a main support method for measurement and test of laser tracking and raging equipment assembly, and give out the results of error slope curve.
