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

然一个特殊的栅反，栅将分散到不同的波长。

Cinematographer Bill Pope built light grids around each bus.

电影摄影师比尔波普在每辆公共汽车周围建造了栅。

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栅和谱分析源的成分。

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 距的狭缝线——这称为衍栅。

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

为此，您需要一个谱仪，一种使用衍栅或棱镜来分离波长的工具。

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

但是，他们也使用栅扫描，每秒多次更新微小的红色、绿色和蓝色像素的亮度。

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

当你通过其中一个栅线时，衍线会更加强烈并且更容易测量。

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.

然花的深色、丰富的部分有一个衍栅，就像你在 CD 上看到的那样，在中心，覆盖在花的中心。

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的硬件来从 RAM 中读取字符，并将们转换成栅图形以绘制到屏幕上。

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 “柱镜栅”的神奇材料，让线有规律地折，直接让自己的双腿消失了。

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.

如果显卡看到字母“K”的 8 位代码，就会将字母 K 的 2D 图案栅扫描到屏幕上的适当位置。
