Charge-coupled device chip

Digital cameras do not contain a film. Instead, a so-called CCD (charge-coupled device) chip takes the picture. This chip consists of separate sensors with red, green and blue filters so that they are sensitive to various colors. The image is not stored by the chip but in a separate memory. The image is then immediately available to be printed out or displayed on a computer...

There are four types of position-sensitive detectors Wire detectors (one- and two-dimensional), video detectors. CCD (charge coupled device chip), and image-plate detectors. The wire detector is bused on the proportional counter principle voltage pulses produced by quanta incident at different points along the wire take different times to reach its two ends. The travel times are derived from the profile of the sum of the two pulses. In the video counter, a phosphor layer generates light flashes where X-ray quanta are incident, and the flashes are picked up by a television camera. The CCD chip is covered by a scintillation foil, which... 

An x-ray area detector can be used to collect the intensities of many reflections at a time. The crystal must be oriented in many different settings with respect to the incident beam but the detector needs to be positioned at only a few positions to collect all of the data. A charge coupled device (CCD) is used as the area detector on the Siemens SMART single crystal diffractometer system. The SMART detector consists of a flat 6-cm circular phosphorescent screen that converts x-ray photons to visible light photons. The screen is coupled to a tapered fiber optics bundle which is then coupled to a one inch by one inch square CCD chip. The CCD chip has 1024 x 1024 pixels each of which stores an electrical charge proportional to the number of...

Recently, an automatic color video image analysis system was developed to quantify antigen expression (androgen receptor) (Kim et al.,T999a). This system provides a linear relationship between the antigen content and mean optical density of the immunoperoxidase-substrate reaction product. Titration of antibody, concentration, and reaction duration of the substrate can be optimized with this system. The imaging hardware consists of a Zeiss microscope, a three-chip charge-coupled-device camera, a camera control board, and a Pentium-based personal computer.
