  2. Image intensifier - Wikipedia

    en.wikipedia.org/wiki/Image_intensifier

    An image intensifier or image intensifier tube is a vacuum tube device for increasing the intensity of available light in an optical system to allow use under low-light conditions, such as at night, to facilitate visual imaging of low-light processes, such as fluorescence of materials in X-rays or gamma rays (X-ray image intensifier), or for conversion of non-visible light sources, such as ...

  3. X-ray image intensifier - Wikipedia

    en.wikipedia.org/wiki/X-ray_image_intensifier

    An X-ray image intensifier (XRII) is an image intensifier that converts X-rays into visible light at higher intensity than the more traditional fluorescent screens can. Such intensifiers are used in X-ray imaging systems (such as fluoroscopes) to allow low-intensity X-rays to be converted to a conveniently bright visible light output.

    The through-the-lens view is displayed on a miniature solid-state screen, rather than on an optical screen or view. [2] EVIL: Electronic viewfinder interchangeable lens camera. See also MILC, mirrorless interchangeable-lens camera. [16] Exif: Exchangeable image file format. A standard format for tag data in digital camera files. [10] f: f ...

    Since the cathode-ray tube in the domestic receiver has an effective gamma value of 2.5, the final screen picture will be at a gamma of 1.0—equal to the original scene. Film is used to supplement television programmes in two ways ; either originating as a telerecording or as a motion picture film.

  6. Fluoroscopy - Wikipedia

    en.wikipedia.org/wiki/Fluoroscopy

    Input phosphor, when the X-rays interact with this piece, its energy is converted into a burst of visible light photons as they occur like this on the intensifying screen/monitor. The photocathode is a thin metal layer, that is usually composed of caesium and antimony compounds that respond to stimulation by the light with the emission of the ...

  7. Latent image - Wikipedia

    On the other hand, a developed silver grain can have billions of silver atoms. Therefore, photographic developer acting on the latent image is a chemical amplifier with a gain factor up to several billion. The development system was the most important technology that increased the photographic sensitivity in the history of photography.

  8. Charge-coupled device - Wikipedia

    en.wikipedia.org/wiki/Charge-coupled_device

    The phosphor screen finally converts the multiplied electrons back to photons which are guided to the CCD by a fiber optic or a lens. An image intensifier inherently includes a shutter functionality: If the control voltage between the photocathode and the MCP is reversed, the emitted photoelectrons are not accelerated towards the MCP but return ...

  9. Photographic processing - Wikipedia

    en.wikipedia.org/wiki/Photographic_processing

    Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image.
