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:
“Thou shalt not, it is said, make unto thee any graven image of God. The same commandment should apply when God is taken to mean the living part of every human being, the part that cannot be grasped. It is a sin that, however much it is committed against us, we almost continually commit ourselves—Except when we love.”
—Max Frisch (1911–1991)
