感光耦合组件 Charge-coupled device

(重定向自CCD imager)
一组用于紫外线影像处理用的CCD
在栅电极(G)中,施加正电压会产生势阱(黄),并把电荷包(电子,蓝)收集于其中。只需按正确的顺序施加正电压,就可以传导电荷包。
使用CCD的Webcam(摄像头)

感光耦合组件,(英语:Charge-coupled Device,缩写:CCD),是一种集成电路,上有许多排列整齐的电容,能感应光线,并将影像转变成数字信号。经由外部电路的控制,每个小电容能将其所带的电荷转给它相邻的电容。CCD广泛应用在数字摄影、天文学,尤其是光学遥测技术(photometry)、光学与频谱望远镜,和高速摄影技术如幸运成像。

Charge-coupled device 感光耦合元件

(重定向自CCD imager)
A specially developed CCD used for ultraviolet imaging in a wire-bonded package
George E. Smith and Willard Boyle, 2009
The charge packets (electrons, blue) are collected in potential wells (yellow) created by applying positive voltage at the gate electrodes (G). Applying positive voltage to the gate electrode in the correct sequence transfers the charge packets.
CCD from a 2.1 megapixel Argus digital camera

A charge-coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for example conversion into a digital value. This is achieved by "shifting" the signals between stages within the device one at a time. CCDs move charge between capacitive bins in the device, with the shift allowing for the transfer of charge between bins.
