But both will have a solid understanding of what happens to light as it travels through the lenses and bounces off the mirrors.

但是两者都需要真正理解光线在透过镜头和从镜子里反射时发生了什么。

Cavities with mirrors spaced specifically to amplify red, blue and green light are grouped in bunches of three, each of which corresponds to a single dot, or pixel, on the display.

为增强红蓝绿光，镜子会隔成特定间距，其空腔分为三束，每束相当于显示屏上的一个单点，或像素。

Newtonian and catadioptric telescopes have secondary (or diagonal) mirrors that obstruct a small percentage of light from the primary mirror.

牛顿望远镜和反射折射望远镜都有一个次级反射镜(或称斜反射镜)，它们阻挡了一部分主反射镜的发射光。

Metal-rubber mirrors would be light and rugged, and would be ideal for use in cameras, space probes or satellites.

ECONOMIST: MONITOR

They are devising ways to send optical signals vast distances without the need for expensive electronic goosing, tinkering with mirrors to switch and bend light in new ways and trimming costs to open up entirely new parts of the telecom infrastructure.

FORBES: Hooked on photonics

These mirrors are hinged and either reflect light or not based on their position.
