INSTANTANEOUS VIDEO DISPLAY OF X‐RAY TOPOGRAPHIC IMAGES WITH RESOLVING CAPABILITIES BETTER THAN 15μ

A silicon diode array target has been used as an image transducer for x rays in a closed‐circuit television system. It is shown that x‐ray topographs of images smaller than 15μ can be displayed essentially instantaneously on a television monitor. In addition, the magnification of the topograph can be controlled electronically and individual video scan lines can be presented on an oscilloscope to give an intensity plot across the x‐ray topograph.
