The purpose of having two systems is that the phosphorescent screen and camera is used to ensure that the electron beam and magnetic lenses are set up properly, as an incorrectly focused beam could damage the sensitive CMOS camera.

拥有两个系统的目的在于使用磷光屏相机来确电子磁透镜设正确，因为聚焦不当的电子会损坏敏的CMOS相机。

The setup and hold times, why are they even there? How can we find out how high they are? The logic gates are nowadays built most of the time, again, in so-called CMOS technology.

设持时间，为什么它们还在那里？我们怎样才知道它们有多高？如今，逻辑门大部分时间都是采用所谓的 CMOS 技术构建的。

When you're ready to capture a high-resolution image, the phosphorescent screen moves out of the way, and the image is captured using the second system with a more sensitive CMOS camera that has a higher resolution and dynamic range.

当您准备捕捉高分辨率图像时，磷光屏会移开，然后使用第二套系统， 该系统配备了一台分辨率动态范围更高的CMOS相机来捕捉图像。
