How does a charge coupled device work
http://www.microscopyu.com/digital-imaging/introduction-to-charge-coupled-devices-ccds WebThe concept of the bucket-brigade device led to the charge-coupled device (CCD) developed by Bell Labs for use in digital cameras. The idea of using capacitors to retain a voltage state has older origins and separately led to Dynamic random-Access memory where the charges are not propagated, but refreshed, in place.
