Definition of image intensifier in English:

image intensifier


  • A device used to make a brighter version of an image on a photoelectric screen.

    • ‘An image intensifier, which is often bonded fiber-optically to the photosensitive CCD of the system, amplifies incident photons and allows detection of low-light signals.’
    • ‘There is also an interface for an image intensifier or thermal imaging sight, allowing the unit to be used in virtually any conditions, day or night.’
    • ‘The setup is similar to that used for fixation of hip fractures, including a fracture distraction table with a well-padded perineal post and an image intensifier.’
    • ‘The lightweight sight and display includes advanced visor projection with image intensifiers and forward looking infrared.’
    • ‘Placement of the needle into the joint can be confirmed with the image intensifier, or may be directly visualized from the arthroscope in the anterolateral portal.’
    • ‘After sunset we affixed image intensifiers with 80-200 mm zoom camera lenses to the video cameras.’
    • ‘In a traditional x-ray detector, known as an image intensifier, x rays produce electrons, which, after being accelerated and focused by an electric field, strike a phosphor screen.’
    • ‘The resolution of particle position in our measurements was limited by noise from the image intensifier and fluctuations in background fluorescence.’
    • ‘As an option the periscope can be upgraded with an image intensifier or other plug-in modules.’
    • ‘Charge-coupled devices also made in Chelmsford were used in image intensifiers - to register crystal clear pictures from the delicately built all-British lander.’
    • ‘It is equipped with a range of modular day and night observation equipment, based on image intensifiers or infrared technology.’
    • ‘Deep-well detectors require an image intensifier to produce a sufficient number of photons to provide ample signal-to-noise.’
    • ‘Imaging with a mobile image intensifier, therefore, has been identified as the optimal radiographic technique for finding retained surgical needles in patients.’
    • ‘A long, thin guide wire with a smooth rounded tip is first inserted and then guided, under X-ray control using a fluorescent screen or a TV image intensifier, into the vessel to be examined.’
    • ‘This color vision is critical to the soldier's ability to read maps and use such devices as image intensifiers.’
    • ‘On the other hand, an image intensifier or electron-multiplying CCD would not assist in overcoming shot noise but only in overcoming readout noise, which we did not consider in our noise estimates.’
    • ‘Passive image intensifiers and thermal imaging equipment for night driving, navigation and weapon deployment permit round-the-clock combat operations.’
    • ‘The patient can usually be positioned supine under the image intensifier, making the approach more comfortable for patient and operator.’
    • ‘Light emitted from the LEDs can be seen by any image intensifier.’
    • ‘These are the image intensifier, operating microscope, arthroscopy, laser, radio frequency, power equipment, and computer-assisted surgery.’
