Publication number: 20220334400Abstract: A method for compensating beam angle variation of a beam bundle of laser beams with respective beam angles includes generating the beam bundle using a diffractive optical element, determining a beam angle value from a beam angle of at least one laser beam of a first subset of the laser beams, detecting a light pattern projected by a second subset of the laser beams, and evaluating the light pattern. The evaluation is performed taking into account the beam angle variation of the beam angles of the second subset of the laser beams on the basis of the determined beam angle value.Type: ApplicationFiled: April 19, 2022Publication date: October 20, 2022Applicant: VITRONIC Dr.-Ing.

Patent number: 9325888Abstract: A method for measuring the height of an object, including projecting a light pattern having successive coded picture elements extending in a direction of a transversal axis onto the object by a light source. Each of the picture elements has at least one coding feature and the picture elements together define a code word. The picture element groups from a sequence of a predetermined number of successive picture elements each define individual partial code words, existing exactly once within the code word. Capturing the light pattern by a picture sensor arranged off-set to the light source. Determining the positions of the picture element groups and determining the height of the object the determined position of the picture element groups in comparison to a respective reference position.Type: GrantFiled: October 29, 2013Date of Patent: April 26, 2016Assignee: VITRONIC Dr.-Ing. Stein Bildverarbeitungssyteme GmbHInventors: Burghard Hoffmann, Ingo Tzschichholtz

Publication number: 20020093667Abstract: The present invention is concerned with monitoring moving operations, with an optical sensor (1) and an illuminating means (12). In order to provide a device for sensing or monitoring moving operations, in which an optimum lighting of the sensing area is ensured even when objects of greatly varying sizes are sensed, or respectively when the distance between the camera and the object to be sensed changes significantly from object to object, it is proposed according to the invention that a first deviation mirror (2, 2′) be arranged such that the light leaving the illumination means (12) is reflected.Type: ApplicationFiled: July 24, 2001Publication date: July 18, 2002Inventor: Burghard Hoffmann

Patent number: 6104427Abstract: A plurality of separate conveyings over each of which a single line camera is mounted and connected to a sensor processor, which itself is connected to a fast data network with a plurality of processing terminals. Because of the high resolution (up to 7000 picture elements per line) and a line scanning frequency of the order of up to 6000 hertz very large amounts of data are received, so in the preferred embodiment a high capacity data network is used, for example a 100 Mbit ethernet with a switching hub.Type: GrantFiled: September 25, 1997Date of Patent: August 15, 2000Assignee: Vitroinic Dr.-Ing Stein Bildverarbeitungssystem GmbHInventors: Norbert Stein, Burghard Hoffmann, Richard Moreth
