Patent number: 11656338Abstract: A reflector arrangement having at least one retroreflector and at least one sensor arrangement arranged downstream of the retroreflector in relation to a beam incidence direction, having a sensor. The sensor arrangement comprises a code element—having a code pattern, and the retroreflector, the code element—and the sensor are arranged in such a way that the code element—is arranged between the retroreflector and the sensor and an angle-dependent position with respect to the optical axis of a projection of the code pattern onto the detection surface can be determined by means of the sensor.Type: GrantFiled: September 19, 2019Date of Patent: May 23, 2023Assignee: HEXAGON TECHNOLOGY CENTER GMBHInventors: Thomas Jensen, Andreas Schwendener, Johan Stigwall

Patent number: 11619491Abstract: A reflector arrangement for determining the position or marking of target points, having at least one retroreflector, and a beam detection unit, by means of which the orientation measurement radiation passing through the retroreflector is acquirable. The beam detection unit comprises a first sensor for generating a signal in dependence on an acquisition of orientation measurement radiation and a first beam guiding unit. The first sensor and the first beam guiding unit are arranged such that a detection field of view for acquiring the orientation measurement radiation is defined, an alignment of the detection field of view around the yaw axis is variable and orientation measurement radiation passing through the retroreflector is acquirable in dependence on the alignment of the detection field of view with the first sensor.Type: GrantFiled: June 27, 2020Date of Patent: April 4, 2023Assignee: HEXAGON TECHNOLOGY CENTER GMBHInventors: Thomas Jensen, Zheng Yang, Andreas Schwendener, Danick Brühlmann, Josef Müller, Johan Stigwall

Publication number: 20210356267Abstract: A triangulation device for measuring a measurement object by a projection of a structured light pattern onto the measurement object. The triangulation device includes a projector projecting the structured light pattern decomposable into different spatial frequencies onto the measurement object. The projector comprises a matrix of pixel elements and a lens system which determines a wavefront with a wavefront aberration from a reference wavefront, and a camera including a lens system and an imaging sensor, the camera being configured to receive the structured light pattern projected by the projector onto the measurement object, and a processing unit configured to provide distance information by evaluating imaging information provided by the camera. The wavefront aberration comprises a primary spherical aberration coefficient Z9, wherein the primary spherical aberration coefficient Z9 is larger than 0.5?, wherein ? is a wavelength of the projected structured light pattern.Type: ApplicationFiled: May 12, 2021Publication date: November 18, 2021Applicant: HEXAGON TECHNOLOGY CENTER GMBHInventors: Andreas SCHWENDENER, Thomas JENSEN, Johan STIGWALL
