The chip has two lasers: one shoots continuously; the other pulses at regular intervals.

一个光器连续不断地发光，而另外一个则以固定的间隔发脉冲。

Our technologies have advanced over the last 20-plus years to include lasers that fire out of the bottom of the aeroplane and those laser beams image the land surface.

在过去的20多年里，我们的技术不断进步，包括从飞机底部发的光，些光束可以拍摄陆地表面的图像。

And NASA has launched the Laser Communications Relay Demonstration (LCRD) mission from Cape Canaveral, Florida.

美国国家航空航天局（NASA）在佛罗里达州卡纳维拉尔角发了光通信中继演示(LCRD)任务。

Eventually, the laser exits the emitter and is passed on to the galvo head, where it's reflected by two mirrors moving as fast as 10,000 millimeters per second, which guide the laser beam to its target.

最终，光离开发器，被传递头，在那里，它被两面以每秒 10，000 米的速度移动的镜子反，光束引导目标。

They fired the laser at each dot in turn, and then fed the data from the spad into an algorithm capable of reconstructing, albeit fuzzily, an image of the hidden object.

他们依次向每个点发光，然后把来自SPAD的数据输入能够重建隐藏物体（尽管是模糊的）影像的算法。

A similar method -- but one considered less dangerous -- would involve shooting laser beams from a spacecraft to destroy the side of an asteroid in an effort to push it away from Earth.

一种类似的方法——但被认为不那么危险——涉及从航天器发光束来摧毁小行星的一侧，试图其推离地球。

The more of these the laser sends in, the more light returns to the device and the higher the resolution of the resulting image.

光器发进去的光越多，反出来的光线也就越多，所成像的分辨率也就越高。

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

些反器现在被用来反从地球发的光束，比如我身后的个。

The technology works like radar, but shoots laser pulses instead of radio waves, to 3-D map a landscape.

项技术的工作原理类似于雷达，但光雷达发光脉冲而不是无线电波，以此来绘制3D地图。

Moments later, lasers from the Predators lit up the vehicles and the Reaper launched its missiles.

片刻之后，捕食者发光照亮了车队，收割者也发了导弹。

So as the plane flies over and shoots a bunch of lasers, the trees actually blow a little, so a couple of the laser beams will get down to the ground surface.

所以当飞机飞过并发一堆光时，树木实际上会被稍稍吹动，所以会有几束光束会达地面。

Because each firing of the laser yielded so little information, the researchers had to take many shots to build up an image.

由于每次光发得出的信息太少，研究人员不得不进行大量拍摄以建构一幅图像。

They were created by shooting lasers at our planet's surface.

它们是通过向地球表面发光而形成的。

But it doesn’t mean you can secretly fire laser beams from your eyes or anything.

但并不意味着你可以偷偷地从你的眼睛或任何东西发光束。

Oh, Deborah, can you add a laser shooter?

哦，黛博拉，能加个光发器吗？

You can shoot a laser at different prisms.

您可以向不同的棱镜发光。

LAGEOS is covered with precision reflectors bouncing back laser beams from ground stations.

LAGEOS表面布满了精密反器，能地面站发的光束反回去。

Shooting lasers at your plasma so that it gets pushed together very quickly.

向等离子体发光，使其快速聚集在一起。

So it's shooting out 640,000 laser pulses per second to fully map the surroundings.

因此，它每秒发出64万次光脉冲，以全面绘制周围环境的地图。

Other ideas for keeping nature at bay include using lasers to generate clouds and for controlling thunderstorms.One idea involved firing laser pulses into thunderclouds in an attempt to suck out lightning in a controlled manner.

其他阻止自然的想法包括使用光产生云和控制雷暴。一个想法涉及向雷云发光脉冲，以试图以可控的方式吸走闪电。
