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.
球差-使以不同孔径角穿过透镜(或从镜面上发射)的光线不能聚焦在轴上的同一点。
Spherical Aberration — causes light rays passing through a lens (or reflected from a mirror) at different distances from the optical center to come to focus at different points on the axis.
德雷克博士说，把这项技术反过来，利用透镜作发射器而不是接收器，能使外星人发送大量强劲信号传遍银河系。
Reversing the technology to use the lens as a transmitter instead of a receiver would enable aliens to beam massively powerful signals across the galaxy, said Dr Drake.
他们也放弃使用任何矫正透镜，而是通过一个针孔发射X光射线，然后采集经过样品后的衍射光线。
They also abandoned using any corrective lenses, firing the X-ray pulse through a pinhole and then collecting the diffracted rays after they pass through the sample.
