1、 Metasurface Optics Applications in Automotive LiDAR and DMS REVA-JUNE2023 Metasurface Optics Applications in Automotive LiDAR and DMS Introduction Optical sensors are rapidly becoming standard equipment on many vehicles.Sensors on the outside of the vehicle,such as light detection and ranging(LiDAR

2、),play a critical role for self-driving cars and driver assisted safety features.Optical sensors on the inside of the vehicle are being used to monitor the driver to determine attentiveness and to interpret gestures.Metalenz is commercializing metasurfaces a new optical element that allows complete

3、control over all aspects of light(phase,wavelength,intensity,and polarization)with a single,planar semiconductor layer.Comprised of subwavelength nanostructures,a single metasurface can carry out optical functions typically requiring four or more conventional refractive and/or diffractive optics.Thi

4、s document will explore the different scenarios in automotive sensing systems both external LiDAR and in-cabin driver monitoring where a solution with Metalenzs innovative optical metasurfaces(meta-optics)can provide cost and performance improvements over traditional optics and whole new insights in

5、to the environment that current cameras and machine vision systems cannot capture.Figure 1:LiDAR and other external sensors on vehicles.External Automotive Sensing In current and future iterations of cars,both traditional and self-driving/autonomous,external sensing plays a critical role in the safe

6、ty and operation of the vehicle.A variety of sensors provide the vehicle with a trove of real-time data about the surrounding environment,enabling the driver and the vehicle itself to make better decisions on the road.Different sensing modalities are used for specific applications and purposes.For M
