Definition of Charge-coupled device (CCD)

1. A CCD is an integrated-circuit chip that contains an array of capacitors that store charge when light creates e-hole pairs. The charge accumulates and is read in a fixed time interval. CCDs are used in similar applications to other array detectors such as photodiode arrays , although the CCD is much more sensitive for measurement of low light levels.
