Compact depth sensing and facial recognition from integration of metasurface and PCSEL (Invited Paper)

In this invited talk, I will report on our latest advancements in depth sensing technology, leveraging the innovative integration of metasurfaces and photonic crystal surface-emitting lasers (PCSELs). Our methodology facilitates facial recognition within structured light technology and enables monocular depth sensing. Compared to existing approaches, our method projects a higher density of infrared dots across a wider field of view, offering substantial benefits for future spatial computing systems. Notably, our system achieves these advantages in a more compact form factor with reduced power consumption. Additionally, our depth-sensing capabilities operate in real-time at approximately 15 frames per second.
