Each radiation source of this multiple radiation source is provided in the form of a separate X-ray tube 1, e.g. having a fixed anode, and placed in a radiation-resistant container 3 filled with oil 2. The X-ray tubes are arranged so as to have an irregular point distribution (so that the distance between adjacent X-ray tubes is not constant), and these X-ray tubes are controlled by a power supply device 4 and a control device 5. . The radiation 7 emitted from the X-ray tube 1 by the iris 8 and passing through the window 6 illuminates the object 9 to be examined and forms a coded image 11 on the detection plane 10 .
