Web4 Theory of Operation of CCD Devices The concept of the CCD image sensor revolves around the operation of a MOS capacitor. An analogy that is often used to describe the operation of CCD device is that of transferring water using buckets. If one thinks of a single bucket as 1 pixel based on a CCD device and that the water is analogous to the photo- WebDec 7, 2024 · A CCD (Charge Coupled Devices) is a highly sensitive photon detector used in moving charges from within a device to an area where it can be interpreted or processed as information (e.g conversion into a digital value). In today’s article, we will examine how CCDs work, the applications in which they are deployed, and their comparative ...
