Controllable variation of the intensity of diffracted X-ray beams and double modulation of such beams for transmission and reception of audio information

Abstract

This paper discusses research devoted to the study of the intensity change of diffracted and transmitted X-ray beams under the action of a temperature gradient or acoustic oscillations, as well as the techniques for `controllable complete reflection' of transmitted X-radiation in the direction of the diffracted beam. Also discussed are results on the double modulation of X-ray beam intensity by acoustic oscillations. A scheme is presented for a practical device for transmission and reception of audio information, in particular speech, with the help of X-ray beams diffracted by perfect single crystals. Finally, there are suggestions for applications of modulated beams in the solution of various problems in physics.
