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 essence of the physicality of the most famous blonde in the world is a wholesome eroticism blurred a little round the edges by the fact she is not quite sure what eroticism is. This gives her her tentative luminosity and what makes her, somehow, always more like her own image in the mirror than she is like herself.”
—Angela Carter (1940–1992)
