Abstract
This work is based on the concept of integrating metasurfaces as passive elements to enhance LiDAR capabilities. We demonstrated a proof-of-concept of a LiDAR imaging system capable of acquire images at 1 million of frames per second using a faster scanner active device with a field of view up to 150°X150°. The active element redirects the light into a metasurface deflector which enhances the field of view. MHz imaging rate and 3D imaging is demonstrated. Finally, we discuss applications and limitations of using such approach, which is a strong candidate to pave the way into full autonomous vehicles.
