The width of the band in the direction of movement is, for example, 6
It is 0m. Advantageously, this width corresponds transversely to the direction of movement to the width of the band. The strip of material is, for example, a conveyor belt used in underground operations. Such conveyor belts are moving at speeds of up to 7 m/s, for example.

して動作する。Structure of the Invention In order to solve this problem, the present invention shows the following. That is, the beam source is driven in pulsed operation with beam pulses of varying pulse width and period T and thus of a predetermined pulse frequency f, with 'VBt
The pulse width s is selected such that s is small, with v
When the B/f is small and the pulse frequency forms a continuous series of transmitted images on the luminescent screen, the images can also be recorded and electronically stored using a digital camera. However, this video camera similarly operates in pulsed operation, and moreover, operates in synchronization with the pulsed operation of the beam source.

ばわけなく実現できる。An X-ray tube can be used as a radiation source within the framework of the invention. Pulsing of the light source is then carried out by applying a suitable cut-off voltage in the form of a pulsed high voltage. In this way, so to speak, X-ray flashing is used. However, it is also possible to use a gamma ray sample as the light source. In this case, the pulse operation is carried out by a rotating shutter (thus, it is advantageous to use a rotary shutter which is cut off according to the period between the windows through which the beam pulses pass. In the method according to the invention, the pulse width is generally controlled according to the period. This can be exploited for the recording of transmission images by a video camera.Therefore, according to the invention, the individual transmission images on the fluorescent screen are stored image by transmission according to the period T. This can easily be achieved using current electronic technology.

You can check it out.

In principle, the pulse width t■ is determined by the desired resolution, which is approximately one in the direction of movement of the strip material. The pulse width t4 therefore does not exceed 150 Msec to suit the purpose. The period T, and therefore the frequency f, is determined by the video camera image repetition, for example 25 frames per second. An image is illuminated during X-ray flashing. An image repetition frequency of 25H2 provides almost sufficient overlap (because, for example, at a band velocity of 7 m/s, the next image is taken after a band movement of 280 h).

設けられている。The advantages of the invention are as follows. Thus, according to the method according to the invention, the transmitted beam of a moving strip of material during continuous non-destructive material testing is resolved into a series of individual images, which can be analyzed by individual image evaluation by screen consideration or automatic image evaluation. It can be performed. In this respect, with the method according to the invention a series of individual images are obtained, the method nevertheless examining the strip material for defects with sufficient accuracy and completeness depending on the resolving power during continuous operation. It is now possible to do so. It is particularly advantageous that sophisticated components and units can be used to carry out the method according to the invention. The device for carrying out the method according to the invention therefore has the following characteristics. That is, X-ray tube 1

３が間に挿入される。The video camera 4 and the X-ray device 1 are connected via a pulsed line 5 device 6. These devices are driven by synchronous pulses. Between the X-ray tube 1 and the fluorescent screen 20 a strip of material 7 is moved continuously, and this material is to be subjected to continuous non-destructive testing while in motion. Here, it may also be a continuously moving conveyor belt used in underground operations. The moving strip 7 moves with a speed VB, which speed is marked in the tooth 1 diagram. To the moving strip material 7,
It can be seen that in this embodiment, the transmitted beam of the beam source 1, which is an X-ray tube, is directed. The beam source 1 has a pulse width t
(2) It is driven in a pulsed manner by a beam pulse having a period T and therefore a predetermined pulse frequency f. The pulse width tI and the period T and the relationship given thereby are shown in Figure 2, in which time is shown on the horizontal axis and the intensity of the transmitted beam is shown on the vertical axis. Regarding the configuration, the pulse width t is the product of VBj and the resolution (e.g. 1 mm
), such that VB/f is small relative to the width of the beam cone measured on the strip 7 in the direction of movement. In this way, a series of continuous transmitted images are formed on the fluorescent screen 2 according to the pulse frequency. The transmitted image on the fluorescent screen 2 is captured by a video camera 4 and stored electronically. An image intensifier 3 is inserted in between.
