Abstract
Reproduction of x‐ray diffraction topographic images has been made at about 25 diameters enlargement by a closed‐circuit television camera system with an x‐ray sensing Vidicon tube which utilizes a beryllium window and PbO photoconductive target. The height of video signals is exactly proportional to x‐ray intensity, and intensity distribution can be observed as a video waveform. It is shown that the television image system can be used for rapid observations of topographic images such as Pendellösung fringes and imperfections in crystals, although its resolution (about 30 μ) is inferior to that of the photographic method.Keywords
