Analytical expressions of coupling frequencies of Raman free-electron lasers are deduced based on the physical image of the coupling between negative-energy space-charge wave and EM wave.

从负能空间电荷波与电磁波耦合的物理图像出发推导了喇曼散射模式自由电子激光器耦合频率的解析表达式。

A microprocessor reads the charge in each pixel as a digital signal and constructs an image of the scene.

微处理器则将每一个像素里的电荷转换成数位讯号，并组成实景的影像。

This microscopic scale and sensitivity allows the sensor to map a high-resolution image of electrical charge that occurs over the surface of a source material (for example a human finger), when it makes contact with a thin insulating surface (ie a plastic surface).

The resulting charge-parity symmetry solved the mirror-image problem in theory.

The key difference is that instead of focusing the light on a strip of photochemical film as in traditional cameras, digital cameras use an image sensor, called a charge coupled device (CCD), to capture the image.
