摘要
介绍了一种用激光作光源输入的光纤笔以ＣＣＤ作为检测时变图形面积的检测系统，采用光学成像技术，计算机图像处理技术，实现了时变图形的实时显示及闭合图形面积的显示，具有实时性强，自动化程度高等优点，将该系统应用于对汽车前窗冰层融化程度的检测，体现了一定的实用价值，对工程上复杂面积的测量，有一定的参考价值。
In this paper,the thermal effect of focussing lens in the laser processing was studied from the theoretical calculation and the experiment.The influence of the thermal effect of focussing lens for the laser welding technolgoy was discussed.Some rules and the preventive methods were obtained.The suggestions of the research shows quite signification to improvt the quality and technology of the laser welding.
