Abstract
A method for the contact-free measurement of the distance of an object according to the principle of laser triangulation, in which a laser beam is directed onto the measuring object and the illuminated region is so imaged on a line-like sensor with prior-arranged optics, which is arranged laterally next to the laser, that the position of the image on the sensor changes with the distance of the measuring object and from the distance of the image from the laser a distance signal is obtained, wherein at least one laser projects a line onto the measuring object and the light plane of the laser line and the observation plane of the line-like sensor form an angle and intersect in a parallax-free cross.
