Abstract
Device for the measurement of the profiles of strand-shaped objects, consisting of at least one light beam source (4), in particular a laser, which runs a spot of light (e.g. 8) over the profile (1) at a beam plane (7, 17) opposite to the strand (1') arranged at an angle (<phi><-e>), and at least one detector module (9), which receives the light reflected by the profile (1), said laser being arranged in the longitudinal plane formed by the strand (1') and the light beam source (4) and trained on the irradiated profile area, and a focusing device (12) focusing the reflected light (23) for a unidimensional receiver row (14) to which an evaluation device (14) is connected. In order to achieve the greatest possible resolution during the measurement, the device is designed in such a way that the reflected light (23) received by the detector module is focused by the focusing device (12) into a concentrated line (13) running transverse to the receiver row (14), and that the reflected light (2 3) is routed to a beam splitter (11) located in front of the focusing device (12), said beam splitter deflecting the light to a second line-concentrating focusing device (12') whose concentrated line (13') runs transverse to a second unidimensional receiver row (14') connected to the evaluation device and running transverse to the first concentrated line (13).
