Sputtered optical coatings for the coaxial integration of sensors in adaptive automotive headlights

With an increasing degree of automation in mobility, the demands on the sensors and the number of sensors in the vehicle are steadily increasing. For sensor integration and combination an efficiently manufacturable compound system including LiDAR, radar and lighting system has been designed. In the pilot project "Smart Headlight" of the PREPARE program of the Fraunhofer Society the Fraunhofer institutes FEP, IOF, ILT, IMS and FHR will prove the integration of such a sensor-lighting combination into automotive headlights under shared coaxial decoupling in driving direction, covering a wavelength range of some nanometers up to millimeters. Optical multilayer coating designs are developed and sputtered at FEP Dresden to demonstrate the feasibility of this coaxial combiner system integrated into the automotive headlight.
