The Apollo missions placed reflectors on the Moon's surface.

阿波罗计划在月球表面安装了射器。

So gold, it turns out, is a great reflector of infrared light.

所以，事实证，黄金是红外线的极佳射器。

So these are all basically full of retroreflectors, right?

所以这些本上都是射器，对吗？

Basically, each of these little squares has 6,000 retroreflectors per square centimeter.

本上，每个小方块每平方厘米有 6000 个射器。

I'm sorry, what? It's pretty cool. We've got a twometer parabolic reflector and everything.

抱歉 什么 很酷的哦 我们准备了直径两米的射器和其他仪器。

Engineers stand on top of scaffolding slotting graphite reflectors into place.

工程师们站在脚手架的顶部，将石墨射器插入指定位置。

Wang Qingming, the telescope's electro-mechanical system's chief engineer, says the size of the reflector is important.

望远镜机电系统的总工程师Wang Qingming表示，射器的大小非常重要。

You can also just have reflectors.

你也可以装备一些射器。

It's actually one of the most ingenious and coolest inventions to ever come about, retro reflection.

这实际上是有史以来最巧妙和最酷的一，射器。

Recruits adorned themselves with headbands bearing motion-capture reflectors… which the researchers used to track their movements.

参与实验的人们戴着带有运动捕捉射器的头带，用于跟踪他们的动作。

Although, I suppose the retroreflector left on the moon by Neil Armstrong does qualify as a shiny object.

尽管我可以确定尼尔·阿姆斯特朗留在月球上的回复射器的确符合了亮晶晶的标准。

These reflectors are used today to reflect back laser beams emitted from Earth, such as this one behind me.

这些射器现在被用来射从地球射的激光束，比如我身后的这个。

And that is a basic 101 of how a retroreflector works.

这就是射器工作的本原理。

To combat this rain visibility problem, 3M actually developed these elements, which are retroreflectors that have different refractive indices.

为了解决雨天能见度的问题，3M 公司实际上开了这些元件，它们是具有不同折射率的逆射器。

But 3M took that principle even further with a full-cube retroreflector.

但是 3M 将这个原理进一步展，创造了全立方体射器。

I think this is an example of a reflector.

我认为这是一个射器的例子。

They bounced lasers off all these reflectors to measure how much the continents were drifting.

他们利用激光在这些射器上弹，以测量各大陆漂移的程度。

So those tiny long wires are signal reflectors.

所以那些细长的电线是信号射器。

Spherical reflectors don't perfectly focus all the incoming rays.

球面射器不能完美地聚焦所有入射光线。

Greasy reflectors of ribbed tin backed them, making quivering disks of light.

油腻的锡制射器在它们背后，形成了颤动的光盘。
