这张NGC 6240（星系）的图片是来自钱德拉（X射线天文台）新X射线数据（如图中红、橙、黄部分所示）和哈勃望远镜于2008年首度公开的一张光学图像两者合成的。
This image of NGC 6240 contains new X-ray data from Chandra (shown in red, orange, and yellow) that has been combined with an optical image from the Hubble Space Telescope originally released in 2008.
光学望远镜在数角秒内就能获取一张星空图—至少比肉眼能获取的大60倍。
Visible light telescopes can resolve a piece of sky just a few arc seconds across — at least 60 times a smaller patch of sky than can be resolved with the human eye.
本文介绍了一种光学成像技术，采用这种技术可以得到一张面目全非的照片。
An optical imaging technique was presented, by which a picture can be changed beyond recognition.
本文从理论上对混合应变量子阱结构(既有张应变量子阱又有压应变量子阱)的光学限制因子进行了讨论。
The polarization dependent optical confinement factor of waveguide structure with mixed strained layer multi quantum well has been discussed in this paper.
如果一张照片抵得上一千字，那么当你开始选购一架数码相机时，你很快会发现：一架数码相机简直就相当于一万页行话连篇、晦涩难懂的光学官样文章。
If a picture is worth a thousand words a digital camera is worth10000pages of jargon double-talk and indecipherable optical gobbledygook as you'll quickly discover when you start shopping for one.
