Charge Coupled Devices (CCDs) were invented in the 1970s and originally found application as memory devices Charge Coupled Devices (CCD) have many applications, but the most important is in imaging. The basic operation of the sensor is to convert light into electrons. When light is Incident on the active area of the image sensor it interacts with the atoms that make up the silicon crystal. The energy transmitted by the light (photons) is used to enable an electron to escape from the tight control of one atom to roam more freely about the device as a "Conduction" electron, leaving behind an atom shy of one electron.
