Abstract
In the illustrated embodiments the undersurface of the thermoplastic coating and the associated electrode are formed with a corrugated structure to produce a correspondingly regularly varying electric field at the exposed thermoplastic surface. The spacing between corrugations is much smaller than the desired x-ray image resolution so that the developed image in effect modulates the regular variation produced by the corrugations. Where the original corrugations are derived from an off-axis zone plate, the developed image can be read out by means of a divergent incident light beam.
