Web Definition: Ccd
A charge-coupled device, is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to one or other of its neighbours. CCDs are used in digital photography & astronomy. When a photon strikes an atom, it can elevate an electron to a higher energy level, in some cases freeing the electron from the atom. When light strikes the CCD surface, it frees electrons to move around & they accumulate in the capacitors. Those electrons are shifted along the CCD by regular electronic pulses & counted by a circuit which dumps the electrons from each pixel in turn into a capacitor & measures & amplifies the voltage across it, then empties the capacitor. This gives an effective black & white image of how much light has fallen on each individual pixel. CCDs containing a single row of capacitors can be used as delay lines. An analogue voltage is applied to the first capacitor in the array & at regular intervals a command is given to each capacitor to transfer its charge to its neighbour.
