Image Intensifier

An 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 to X-rays or gamma rays, or for conversion of non-visible light sources such as near-infrared or short wave infrared to visible.

Famous quotes containing the word image:

    The island dreams under the dawn
    And great boughs drop tranquillity;
    The peahens dance on a smooth lawn,
    A parrot sways upon a tree,
    Raging at his own image in the enamelled sea.
    William Butler Yeats (1865–1939)
