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 light of memory, or rather the light that memory lends to things, is the palest light of all.... I am not quite sure whether I am dreaming or remembering, whether I have lived my life or dreamed it. Just as dreams do, memory makes me profoundly aware of the unreality, the evanescence of the world, a fleeting image in the moving water.”
—Eugène Ionesco (b. 1912)
