Abstract

Continuous, non-destructive materials testing of strip material (7), moving continuously at a velocity vB, particularly of continuously-running conveyor belts, is effected by directing a beam (8) of penetrating radiation from a source (1) of radiation at the moving strip material and the picture produced by the penetrating radiation material is made visible on a fluorescent screen (2), the beam of penetrating radiation forming a radiation cone possessing on the strip material a width b in the direction of movement of the strip material, the radiation source being operated by an impulse drive (6) with pulses of radiation of impulse duration tI with a period duration T and a thereby specified pulse frequency f, the impulse duration tI being so chosen that vBtI is small compared with a desired picture resolution, and vB/f being small compared with the width b of the cone of radiation on the strip material in its direction of movement and, in accordance with the pulse frequency of, a continuous succession of penetrating radiation pictures on the fluorescent screen being recorded by means of a video camera (4) and stored by recording equipment (5) the video camera also being impulse-driven synchronously with the impulse drive of the radiation source.
