Abstract
This Light Amplifying Panel, a sandwich of photoconductive and electroluminescent layers, operates as either a positive or negative image intensifier, depending on amplitude and phase of its two power supply voltages. The panel amplifies visible light infrared, or x-ray images. Amplified output image is continuously variable from a positive-intensified reproduction of the original to its negative image similarly intensified. Control of gamma and brightness over a wide rage is possible at the same time.
