charge coupled device
CHMO:0000948
A piece of apparatus, based on a semiconductor chip, which converts the intensity of light falling onto its surface at different points into a charge. When a photon is absorbed by the chip, a single electron is released. Electrodes covering the chip surface hold these electrons in place in an array of wells, or pixels, so that during exposure of the chip to light, a pattern of charge builds up that corresponds to the pattern of light.
