Abstract:
In order to study the distribution of the electron densities in the laser-induced-plasma(LIP),the image-processing methods are utilized to pre-process the interference fringes of laser-induced-plasma.The interferograms of the LIP is obtained by Mach-Zehnder interferometer in experiment.The interference fringes of the LIP are pretreated by filtering and sharpening.In order to get the thinning-image of the interference fringes of the LIP,binary and thinning are used to treat the denoised interferograms of the LIP.The inverse Abel transform is operated on the shift of the thinned interference fringes,and the radial distribution of electron density of the LIP is obtained.
