A device that uses fibre optics to increase the sensitivity of a pick up tube.
A device that uses light sensitive phospor screens to intensify light, and improve camera performance in low light conditions
An electronic device which is used to amplify small amounts of light into usable amounts of light to produce a video picture. The device uses very high voltages to accelerate photons in a vacuum tube. The device is placed between a lens mount and an image device such as a vidicon or CCD. The lenses used on cameras with intensifiers must have special attributes with f-stops of up to f/1200.
An electronic device used to provide an output image that is brighter than the input image.
An electronic device that provides a brighter image than that produced by the unaided action of an X-ray beam on a flourescent screen.
An electronic attachment to a lens system that amplifies incoming light. Also called night viewing device.
is a device which intensifies light by using light sensitive phosphor screens. It is used to improve camera performance under low light conditions.
A device coupled by fiber optics to a camera image pickup sensor to increase sensitivity.
A device similar to the light-sensitive cathode-ray tube in a television camera, and which responds to a single electron displacement caused by the impact of electromagnetic radiation producing thousands of times as many electrons, thereby intensifying a faint image into a brighter image when the larger number of electrons strike a surface that glows upon electron collision.
A vacuum-tube device, generally 18 to 25 mm in diameter, that comprises a photocathode input (a coating of multi-alkali or semiconductor layers on the inside of the input window) and a phosphor screen (a fluorescing phosphor coating on the inside of the output window). Also included are either simple grid-shaped electrodes (early intensifier technology) to accelerate electrons through the tube or a complex electron-multiplying microchannel plate (later intensifier technology).
An image intensifier is a device that amplifies visible and near-infrared light from an image so that a dimly lit scene can be viewed by a camera or by eye. Unlike a thermographic camera, an image intensifier does not work in the total absence of visible (or near infra-red) light. It does, however, create a more realistic image, because the intensities it shows are related to true optical intensity and not to temperature.
