Apparatus for the all-round X-ray testing of a rotatably supported vehicle tyre (10, 11) during one tyre rotation which has an omnidirectional X-ray tube (16) arranged in the space enclosed by the tyre near its open inner side in such a way that the radiation originating from it irradiates the tyre side walls (12, 13) and the tyre running surface (14) from the inside outwards, three linear diode arrangements (17, 18, 19) of photosensitive diodes arranged outside the tyre, preferably parallel to the diameter or the axis, a scanning device (24) which is assigned to the diode arrangements and scans the diodes at a specified but variable scanning frequency and feeds the output signals of the diodes to a memory (25), and a display device (20) consisting of single image points for producing one image line in each case for one diode arrangement per scanning sequence, the diodes being arranged at a distance which produces a high resolution and makes textile inlays, in particular, in the tyre visible. This distance is preferably equal to or less than 0.5 mm and a switching device (80) is assigned to the scanning device in such a way that optionally only every second, third, etc. diode is scanned at a specified scanning frequency during a scanning sequence. …<IMAGE>… |
