Multifunctional metalenses accurately construct 3D scenes

A line of metalenses, which are flat diffractive optical elements, achieves multiple optical functions on a single surface for a broad wavelength range.

A line of metalenses, which are flat diffractive optical elements, achieves multiple optical functions on a single surface for a broad wavelength range. In one implementation, they both collimate and split the light from VCSELs into a uniform grid of thousands of infrared beams that are projected on the scene. Optical sensors reference these grids to accurately construct the scene in 3D.
