摘要: 通过对背光激光的选择,基于光的偏振原理建立了一套高速摄像光学系统.针对电弧与熔滴拍摄的差异性,在没有背光源与有背光源时,分别采用不同的光学元件对弧光进行抑制,并在实际焊接的拍摄过程中取得了较好的拍摄效果.

Abstract: Through the selection of laser for backlight, this paper established a set of highspeed photography optical system based on light polarization principle. Considering the difference between arc shooting and droplet shooting, the system suppress the arc light using different ways based on the principle of optical polarization when there is a backlight or not. The system does a good job in the following welding practice.
