What is a CCD detector and how do they work?

A CCD, or Charge-Coupled Device, is a device which transports analog electrical signals through a series of successive capacitor stages, controlled by a clock signal. In the case of a CCD detector, the signals consist of the output of an array of photoelectric light sensors. Thus, the CCD serialises the parallel analog signals from such an array detector, permitting its use as an image sensor. Good descriptions of the operation of CCDs may be found here and here.
