It then bounces off a special grating that disperses light into its different wavelengths.

然后它被一个特殊光反射，光将光分散到不同波长。

Webb observed two transits of the  exoplanet using its NIRSpec G395 H grating.

詹姆斯·韦伯太空望远镜使用其近红外光谱仪G395 H光观测了这颗系外行星两次凌日现象。

Here we're shining a green laser through a diffraction grating that has 500 lines per millimeter.

这里我们使用一束绿色激光穿过每毫米有500条刻线衍射光。

We're then going to have a grating and the detector now is going to be a camera.

然后我们将有一个光，探测器现在将是一个照相机。

Now, you can also shine light through many equally spaced slits -- this called a diffraction grating.

现在，您还可以通过许多等 间距狭缝照射光线——这称为衍射光。

But today, you learned about how to analyze the composition of a light source using diffraction grating and spectroscopy.

但是今天，您了解了如何使用衍射光和光谱分析光源成分。

The astute among you might ask about the higher order beams from a diffraction grating.

你们中敏锐人可能会问关于衍射光光线问题。

But, they use raster scanning too, updating the brightness of little tiny red, green and blue pixels many times a second.

但是，它们也使用光扫描，每秒多次更新微小红、绿、蓝像素亮度。

So that's the packaged lesson about diffraction gratings, but now let's zoom out and remember why we were doing this.

所以这就是关于衍射光总结，但现在让我们放大视野， 记得我们为什么要这样做。

To do that, you need a spectrometer, a tool that uses diffraction grating or a prism to separate the wavelengths.

为此，您需要一个光谱仪，一种使用衍射光或棱镜来分离波长工具。

And when you shine a light through one of these gratings, the diffraction lines are much more intense and easier to measure.

当你通过其中一个光照射光线时，衍射线会更加强烈并且更容易测量。

In our simple point example, that would correspond to the zeroth order beam from the diffraction grating off the zone plate.

在我们简单点状例子中，这对应于衍射光从区板上产生零级光束。

So if you shine white light through a diffraction grating like this, you get a separation into distinct wavelengths, distinct colors like a rainbow.

所以， 如果你让白光透过这样衍射光，就会分离成不同波长，形成像彩虹一样不同颜色。

And then you put the pixels together in some raster order, and then that's how you get out or in the image that you're processing.

然后你按照某种光顺序将这些像素组合起来，这样你就得到了正在处理图像。

Then the dark, rich part of the flower has a diffraction grating, such as you'd find on a CD, in the center, overlying the center of the flower.

然后花深色、丰富部分有一个衍射光，就像你在 CD 上看到那样，在中心，覆盖在花中心。

Additionally, if you're curious as to how video game graphics work, we have a separate video that explores all the steps such as vertex shading, rasterization, and fragment shading.

另外， 如果你好奇视频游戏画面是如何工作，我们有一段单独视频详细介绍了所有步骤，比如顶点着色、光和片段着色。

Chu demonstrated the " invisibility" at the event, and he made his legs disappear directly with the help of a magical material called " lenticular grating" that allows light to be refracted regularly.

褚在活动现场演示了 " 隐形" ，他借助一种名为 “柱镜光”神奇材料，让光线有规律地折射，直接让自己双腿消失了。

To pull this off, computers needed an extra piece of hardware that could read characters out of RAM, and convert them into raster graphics to be drawn onto the screen.

为了实现这一点，计算机需要一个额外硬件部件，该部件可以从随机存取存储器中读取字符，并将它们转换为光图形以绘制到屏幕上。

Then if you want it to narrow the spacing of the grating, making d smaller, the only way to keep that leg locked is to make the angle theta bigger.

然后如果你想减小光间距，使d变小， 唯一保持那个腿锁定方法是增大角度θ。

If the graphics card saw the 8-bit code for the letter " K" , then it would raster scan the 2D pattern for the letter K onto the screen, in the appropriate position.

如果显卡看到了字母“K”8位代码，那么它就会进行光扫描，将字母K二维图案显示到屏幕上适当位置。
