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.

The motivation for this technique comes from studying the typical scenario of light propagation where short wavelength light travels along rays that minimize ( more or less ) its travel time.

This can arise from a cornea with not enough curvature ( refractive hyperopia ) or an eyeball that is too short ( axial hyperopia ). This can be corrected with convex lenses which cause light rays to converge prior to hitting the retina.

However, since there is a short time delay between the beta decay and the high energy gamma emissions and the third and fourth gamma rays, it is said that the lower energy gamma rays are delayed.

The foregoing factors are pertinent to the analysis of perceptual images and the broad conditions under which they achieve realism or fall short of it.

Over a relatively short period of time, usually about four to twelve weeks, the worker must be able to shift the focus, back and forth, between immediate external stressful exigencies ( `` precipitating stress '' ) and the key, emotionally relevant issues ( `` underlying problem '' ) which are, often in a dramatic preconscious breakthrough, reactivated by the crisis situation, and hence once again amenable to resolution.
