kuvaintensifioija
A kuvaintensifioija, often translated as an image intensifier, is an electronic device used to brighten faint images. It works by converting incoming photons, such as those from dim light or X-rays, into electrons. These electrons are then amplified by a microchannel plate or similar technology, producing a much larger number of electrons for the same number of photons. Finally, these amplified electrons strike a phosphor screen, which emits visible light. This process significantly increases the brightness of the original image, making it visible or easier to observe.
Kuvaintensifioijat have found applications in various fields. In astronomy, they are used to capture images of
