How a Charge Coupled Device (CCD) Image Sensor Works

How a Charge Coupled Device (CCD) Image Sensor Works50 YEARS of the CCDTELEDYNE IMAGING2 area defined by one of the pixels will be converted into one (or more) electrons and the number of electrons collected will be directly proportional to the intensity of the scene at each pixel. When the CCD is clocked out, the number of electrons in each pixel are measured and the scene can be reconstructed.(Above) Teledyne e2v CCD47-20 back- illuminated 1024 x 1024 pixel m pixel Boyle and George E. Smith invented the Charge - Coupled Device (CCD) in 1969 in the United States at AT&T Bell Labs. In 1970, Boyle and Smith submit-ted a paper on their invention of the CCD to the Bell System Technical Journal. Their original ideas for the CCD was to create a memory Device . However, with the publication of Boyle and Smith s research in 1970, other scientists began experimenting with the technology on a range of appli-cations. Astronomers discovered that they could produce high-resolution images of distant objects, because CCDs offered a photosensitivity one hundred times greater than film.
