The basic theory of Gaussian function decomposition of laser waveform data was studied,and the method of fitting pulse waveform by using generalized Gaussian model function was proposed,and the way of extracting important parameters of pulse waveform also was put forward.The testing results show that the Gaussian function of the laser waveform data can better decomposed the pulse waveform,and the parameters extraction method had better robustness when the waveform with higher amplitude was decomposed,and not only increased the number of point cloud,but also increased the level of cloud sense,a...
