Electron Multiplication CCD Cameras (EMCCD)
An electron multiplication CCD camera is a CCD device in which a solid-state electron multiplying register has been added to the end of the normal serial register. The electron multiplying register allows weak signals to be multiplied before readout noise is added by the output amplifier.
  • TERMS
  • camera A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control...
  • charge-coupled device (CCD) A self-scanning semiconductor imaging device that utilizes MOS (metal-oxide semiconductor) technology, surface storage and information transfer. It consists basically of a metal insulator semiconductor (MIS) capacitor, majority carriers being...
  • electron multiplying CCD (EMCCD) A CCD device in which a solid-state electron multiplying register has been added to the end of the normal serial register. The electron multiplying register allows weak signals to be multiplied before readout noise is added by the output amplifier.
  • channel electron multiplier (CEM) A photoelectric detector consisting of a glass tube internally coated with a low conductance material. Voltage applied along the tube causes photoemission from the photocathode at the end of the tube exposed to the radiation, accelerating emission...
  • CCD
  • digital camera A camera that converts a collected image into pixels that are black or white digital or shades of gray. The digital data may then be manipulated to enhance or otherwise modify the resulting viewed image.
  • electron A charged elementary particle of an atom; the term is most commonly used in reference to the negatively charged particle called a negatron. Its mass at rest is me = 9.109558 x 10-31 kg, its charge is 1.6021917 x 10-19 C, and its spin quantum number...
