    • The present invention relates to a method for contactless dynamic detection of the profile of a solid body, particularly a moving one, a laser beam, expanded to form a linear light band, from a laser device being projected onto a region of the surface of the solid body, and the light reflected therefrom being focused in an imaging device, whose optical axis is at a fixed triangulation angle to the projection direction of the laser device and that is arranged at a fixed base distance from the laser device, and is detected by means of a planar light receiving element, in particular at a frequency that is high by compariosn with a speed of movement of the solid body, whereupon signals output by the light receiving element are used in a data processing device as a function of the triangulation angle and the base distance to obtain the measured values of the profile by means of geometric relationships, the values being stored as a profilogram.
