Abstract (en)
[origin: US4680461A] An apparatus and method for obtaining a memory function in picture intensifier or amplifier tubes by providing such tubes with an output screen formed of an electroluminescent cell. This cell emits visible light rays when an electric voltage is applied between its surfaces, and possesses hysteresis properties. When voltage is applied to the screen, the picture sent by the electron beam is stored, and re-established when desired, for a given period. The invention can be applied to radiology.
