Abstract

The invention relates to a method for contactlessly and dynamically detecting the profile of a solid body. At least one light beam is generated by a laser device and expanded to form a linear light band projected onto the moving surface of the solid body. Light reflected from the surface of the solid body is focused in an imaging device whose optical axis is at a fixed triangulation angle to the direction of projection of the laser device and which is arranged at a fixed based distance from the laser device. The reflected light is detected by a planar light receiving element at a frequency that is high by comparison with a speed of movement (v) of the solid body after which the measured values of the profile are obtained as a function of the triangulation angle and the base distance.
