Publication number: 20220299609Abstract: The present invention relates to a laser scanner, comprising a housing, a laser transmitter including a transmission aperture for a transmission beam, a laser receiver for a reception beam, and a beam deflection device in the form of a mirror pyramid, the pyramid axis of which forms its axis of rotation, and the pyramid sides of which each form a mirror facet The laser transmitter and the laser receiver are each directed at the mirror pyramid parallel to the axis of rotation of the mirror pyramid. The laser receiver comprises at least one converging lens arranged downstream of the mirror pyramid in the reception beam path. The converging lens, viewed in the direction of the axis of rotation, in its region of overlap with the mirror facets, is at least as large, in area comparison, as twice the largest of all mirror facets viewed in the direction of the axis of rotation.Type: ApplicationFiled: August 11, 2020Publication date: September 22, 2022Applicant: RIEGL LASER MEASUREMENT SYSTEMS GMBHInventors: Rainer REICHERT, Peter RIEGER, Martin PFENNIGBAUER, Johannes RIEGL

Patent number: 10126425Abstract: The present application relates to a device for object protection, including at least two laser scanners, which are configured to each emit a laser beam scanning fan in front of the object and to detect a penetration of the scanning fan by a body by means of a reflection of the laser beam of the scanning fan on the body. The laser scanners are arranged on a ground next to the object and have laser beam scanning fans that are oriented upwardly. At least one of the laser beam scanning fans is oriented upwardly at an incline. The laser beam scanning fans intersect one another and the laser beam scanning fans form a closed scanning hood covering the object.Type: GrantFiled: January 28, 2016Date of Patent: November 13, 2018Inventors: Ursula Riegl, Johannes Riegl, Martin Pfennigbauer

Patent number: 8995577Abstract: Apparatus for measurement of the reception time of a pulse in a receiving system, which contains at least one receiving channel with a non-linear transmission response, which receiving channel produces at its output a received signal, having a memory, in which the received signals of reference pulses with a predetermined different amplitude are available as reference signals with respect to a time scale, and having an evaluation device, which is connected to the receiving system and to the memory and compares a received signal with each reference signal with a variant time offset in order to determine that reference signal and that time offset for which the comparison discrepancy is a minimum, and outputs this time offset as the reception time with respect to the time scale.Type: GrantFiled: April 14, 2009Date of Patent: March 31, 2015Assignee: Riegl Laser Measurement Systems GmbHInventors: Andreas Ullrich, Martin Pfennigbauer, Walter Schubert, Wolfgang Zierlinger, Andreas Hofbauer, Gerhard Ederer

Patent number: 8307705Abstract: Method for laser hydrography in which at least one laser beam is emitted from a known location and in a known direction onto the surface of a body of water and through the water onto the bottom of the body of water and measurement points of the water surface and the water bottom in a coordinate system are determined from transit-time measurements of the reflections of the laser beam at the water surface and water bottom, wherein the local inclination of the water surface at an entry point of the laser beam into the body of water is determined from at least three measurement points of the water surface, wherein a local entry angle of the laser beam into the body of water is determined from the local inclination and the known direction of the laser beam, and wherein the measurement point of the water bottom is created as a function of the laser beam direction, the local inclination, and the optical refraction due to the corresponding local entry angle of the laser beam.Type: GrantFiled: June 16, 2010Date of Patent: November 13, 2012Assignee: RIEGL Laser Measurement Systems GmbHInventors: Andreas Ullrich, Martin Pfennigbauer

Patent number: 7697120Abstract: A scanning apparatus for use in a scanning optical system comprises a laser transmitter to produce a transmitter beam. This transmitter beam is deviated by a beam scanner, e.g. a tiltable mirror, to produce a pattern of a scanning beam. There are bearings which define first and second axes of rotation perpendicular to each other and intersecting each other in an intersecting point for allowing the beam scanner to scan. In front of the beam scanner is a window of transparent material in the shape of a spherical cap so as to define a central axis and a central point. The central axis intersects the intersecting point of the two other axes, and this common intersecting point coincides preferably with the central point of the sphere of the window.Type: GrantFiled: November 27, 2006Date of Patent: April 13, 2010Assignee: Riegl Laser Measurement Systems GmbHInventors: Rainer Reichert, Andreas Ullrich, Martin Pfennigbauer, Johannes Riegl
