Abstract

In this study, the method of three-dimension reconstruction of laser welding plasma on the basis of three-dimension synchrony high-speed photo is proposed. The method of anti-RADON transformation is used to finish three-dimension reconstruction. The anti-RADON transformation utilizes the projected data to reconstruct the initial image, which bases on the projection of the parallel beam. It is found that there are the cavitations on most section images and the area of cavitations is ever-changing. The space shape of plasma represents irregularity on the different surface.
