charge-coupled device |
Also found in: Encyclopedia, Wikipedia | 0.06 sec. |
charge-coupled deviceDevice for forming images electronically, using a layer of silicon that releases electrons when struck by incoming light. The electrons are stored in pixels and read off into a computer at the end of the exposure. CCDs are used in digital cameras, and have now almost entirely replaced photographic film for applications such as astrophotography, where extreme sensitivity to light is paramount.
