Patent number: 9720090Abstract: A driver assistance system (12) comprises an optical detector (14) with active scene illumination. The optical detector includes at least one of a stereoscopic imager, a time-of-flight imager, a structured-light imager and a night vision system. The optical detector includes a light source (16) for converting electrical energy into light, projection optics (18) for illuminating a scene with light generated by the light source and one or more optical sensors (20) for detecting light returned from the scene in response to the scene being illuminated. The light source is thermally connected to a heat sink (30) for evacuating heat produced by the light source and the projection optics are optically connected to the light source with one or more optical fibers (22) for transport of light generated by the light source to the projection optics.Type: GrantFiled: July 16, 2013Date of Patent: August 1, 2017Assignee: IEE International Electronics & Engineering S.A.Inventor: Norbert Herschbach

Patent number: 9606237Abstract: A spatially coded structured light is generated by an array of laser diodes (1) in order to perform structured light triangulation. The laser diodes (1a-c) are VCSEL, where the light is emitted in the direction perpendicular to the semiconductor wafer surface. Plural such laser diodes (1a-c) are integrated monolithically to form an array (1). The position of the individual laser diodes in the array is coded spatially to form a non-regular unique pattern. The light output by the lasers is projected by a refractive or diffractive optical system (2) into the space to be monitored to form the structured light pattern. An object (5) to be investigated may be illuminated by the VCSEL array (1) and a camera (3) captures the frames. A processing unit (4) controls the power of VCSEL (1a-c) and processes the data from the camera (3).Type: GrantFiled: March 1, 2013Date of Patent: March 28, 2017Assignee: IEE International Electronics & Engineering S.A.Inventors: Norbert Herschbach, Jean-Luc Kaiser
