摘要
利用暗场成像原理,研制成功一套应用于大型激光装置的光学元件损伤在线检测装置,并在多程放大系统上进行了实验研究.与传统的检测手段相比,该检测装置可以实现对光学系统的在线检测,并可对损伤点的图像进行分析处理,最后提出通过减小像差和扩大检测范围的方法来改进该装置的检测效果.
Abstract
An online inspection apparatus of optics damage in large scale laser facility is developed applying dark-field imaging technology.Experiments were carried out on a multi-pass amplifier.Optical defects,such as film damage,self-focusing filament and cranny on optical elements are inspected.Experimental results show that this apparatus can be used for online inspection of optics damage.Further improvements.that the image aberration should be decreased and the inspection range be extended are proposed.
