Apparatus for transmitting signals
In the exemplary embodiments, a ring made of light-conductive material curved around the center of rotation is provided, onto the surface of which a light source radiates, which emits light signals corresponding to the signals to be transmitted. The light -conductive ring is formed in such a manner that it passes on the incident light over its entire periphery and has at least one point of interruption on which a light receiver is arranged. The invention is particularly suited for use in a computer-tomograph, in which an x-ray source and a detector for scanning the radiography subject at different projections rotate around the radiography subject, and data processing equipment determine an image of the examined transverse layer of the radiography subject from the detector signals. In this case the light-conductive ring can transmit the detector signals to the stationary part.
