Abstract: A device for contactlessly determining the straightness of at least one long product, where punctiform or linear measuring radiation is moved by a radiation source module over the long product at least transversely to the longitudinal direction of the long product during a measuring cycle. The intensity of detection radiation coming from an area of incidence of the measuring radiation is recorded by a radiation detection module in a time-resolved manner and is supplied to a control and evaluation unit. The spatial position of the areas of incidence and thus the straightness of a long product can be determined from location information regarding the areas of incidence in the longitudinal direction and from characteristic intensity values of the detection radiation. For a calibration, a reference straightness can be determined by carrying out multiple measuring cycles by rotating a long product of unknown straightness.
