Abstract

Device for measuring the inner walls of deep holes using the principle of a triangulation distance measuring sensor, comprising a display of a sensor with a laser spot position sensor (1) and its imaging optics (2) with the object plane (3) of the imaging optics (2) inclined to the selected optical axis (8) display by an angle (φ), and the direction of the illumination laser beam (4) is at an angle less than the angle (φ), at least one optical element (4) is arranged during the operation of the illumination laser beam (4) there is at least optical member (5) in the dividing and / or changing the direction of travel of the illumination laser beam (4) towards the measured surface (M) so that this beam emerges from the intersection (O) of the thus oriented illumination laser beam (7) and the object plane (3) of the optics (2) and the image mirroring surface (6) of the optical member is placed to form a mirror, image-oriented illumination laser beam (7) affecting on the measured surface (M) in the object plane (3) of the image optics (2).
