Patent number: 11921409Abstract: A light projector and method of aligning the light projector is provided. A light projector steers an outgoing beam of light onto an object, passing light returned from the object through a focusing lens onto an optical detector. The light projector may generate a light pattern or template by rapidly moving the outgoing beam of light along a path on a surface. To place the light pattern/template in a desired location, the light projector may be aligned with an electronic model.Type: GrantFiled: June 25, 2021Date of Patent: March 5, 2024Assignee: FARO Technologies, Inc.Inventors: Maxime Isabelle, Matthew T. Armstrong, Salvatore DiAngelus, Leonardo Martinez, Joel H. Stave

Patent number: 10432903Abstract: A laser projection system is provided. The laser projection system includes at least one laser projector having a laser source and a laser detector. The system includes processors for executing computer instructions, the processors are coupled to the laser projector, the computer readable instructions include determining the component is stationary based on the emitting of a first laser light towards a reference target on the component and receiving a portion of the first laser light by the laser detector. In response to the determining the component is stationary: determining a transformation for mapping a first coordinate system of the laser projector to a second coordinate system of the component and forming a visual pattern on the component. The computer instructions further include determining that the component is in motion based on receiving a portion of the first laser light by the laser detector and removing the visual pattern.Type: GrantFiled: November 7, 2017Date of Patent: October 1, 2019Assignee: FARO TECHNOLOGIES, INC.Inventors: Steven P.

Publication number: 20190064324Abstract: A laser radar projection system is provided. The system includes a laser projector that projects a light beam. A beam splitter is arranged to receive the light beam from the projector and divides the light beam into a signal light beam and a reference light beam. A steering system changes the direction of the signal light beam and scans the light beam over at least a portion of the surface. An optical signal detector is arranged to receive a feedback light beam and the reference light beam. The optical signal detector generates a feedback signal in response to the feedback light beam and a reference signal in response to the reference light beam. One or more processors determine the distance to one or more points on the at least a portion of the surface based at least in part on the feedback signal and the reference signal.Type: ApplicationFiled: August 13, 2018Publication date: February 28, 2019Inventors: Steven Paul Kaufman, Kari J. Mettinen, Masoud Mohazzab, Arkady Savikovsky, Joel H. Stave

Patent number: 9826207Abstract: Techniques are disclosed for tracking the position of moving parts and assemblies using 3D laser projection, and projecting templates and other information onto the parts and assemblies based on position. The projected template may then be used, for example, to assist in fabrication of an assembly by indicating where to put a next component or layer, or to assist in post-fabrication inspection of an assembly by indicating where the various components or layers should have been placed. Reference targets can be used as fiducial points for aligning a laser projector with the work piece in question. When the work piece rotates or is otherwise moved to a next manufacturing or inspection position, the relative position of the laser projector and the work piece is updated by bucking-in to the reference targets. The laser projector can then project patterns or other information onto the work piece at the appropriate locations.Type: GrantFiled: August 22, 2016Date of Patent: November 21, 2017Assignee: FARO TECHNOLOGIES, INC.Inventors: Steven P.
