它通过光导电缆发射激光给机器人，机器人用它手臂末端的角度透镜和镜子对准激光点焊接。
It transmits a laser beam through an optical cable to a robot, which angles lenses and mirrors in the end of its arm to aim the laser towards the parts that need welding.
光线在确定合适角度以后，经透镜底部较薄处折射后从透镜前端发出。
Light enters at the thinner, bottom end of the lens and bounces around until reaching the desired Angle and emerging from the front of the lens.
透镜底部的摄像头通过收集反射回来的光线定位观众的位置，同时发光二极管的角度根据观众的移动发生改变。
A camera at the bottom of the lens tracks the viewers by collecting light coming the other way through the lens and the Angle of the LEDs changes to correspond to the viewers' movements.
介绍了一种利用光栅的多缝衍射分光代替传统转角法的角度测量的微透镜焦距测量方法。
A new method of microlens focal length measurement by rotation method based on grating diffraction is introduced.
半导体激光器发出的激光经过柱透镜形成一出射光片。它与母材成一定角度投射到接头上，光片与搭接接头会成一单光纹，而母材垂直上方的CCD摄像机拍摄折线光纹，同步送计算机处理。
The light-plate that is shot by semiconductor laser comes to a certain Angle to throw overlap joint, which brings a single vein of light, and CCD camcorder shoots and sends it to the computer.
