Scientists at the Luxembourg Institute of Science and Technology list for short combined a specially designed spectrometer with a commercially available helium ion microscope to build a very high-resolution optical device capable of looking into these tiny worlds.

通过将特殊定制分仪与市面上氦离子相结合，来自卢森堡理工院科家制造了一个能够探索型世界仪器。

In the case of a telescope, the “bucket” is an optical device like a lens or a mirror that collects light.

对望远来说，“水桶”就是一种像透单面一样收集线装置。

The big question is: Did he use a Camera Obscura, an optical device to paint this?

他画这幅画是否用了暗箱这种装置？

AO systems use minutely adjustable mirrors and other optical devices, but they also rely heavily on computers to filter out the atmospheric noise from images.

自适应系统使用调和其他设备，但也依赖计算机来过滤图像中大气噪声。
