发明名称 ELEKTRORADIOGRAFISK UPPTECKNINGSANORDNING
摘要 An electroradiographic display with a high picture quality at low radiation intensities is obtained with a device consisting of a source of X-rays, an electrode passing X-rays, an intermediate recording space for an object to be displayed, an electrode on the side remote from the recording space on which a layer of dielectric material is disposed, and a second electrode with a photoconductive layer. The layers are separated by a gas gap which is bounded by one or more side walls. A direct voltage source is in electrical contact with the electrodes. The photoconductive layer comprises a granular photoconductive material in a binder. The gas gap between the dielectric layer and the photoconductive layer is from 50 to 500 mu m wide and the electrode passing X-rays has a surface resistance between 103 to 108 Ohms.
