Abstract
An imaging tube having a fiber optic plate (FOP) as an output faceplate. On one surface of the FOP within an evacuated envelope is deposited a first transparent conductive layer. On the first transparent conductive layer is deposited a fluorescent layer. On the fluorescent layer is deposited a metal-back electrode. On the other surface of the FOP outside the evacuated envelope is deposited a second transparent conductive layer. The first transparent conductive layer and the metal-back electrode are electrically connected so that an electrical field is not developed across the fluorescent layer when the metal-back electrode is applied with a high positive voltage and the second transparent conductive layer is grounded. Therefore, even if leakage currents flow through the FOP, electric charges impinging upon the first transparent conductive layer will not cause the fluorescent layer to generate noise spots.
