# Wide field-of-view metasurface optics, sensors, cameras and projectors

## Abstract

A wide field-of-view sensor or projector includes a transparent substrate with one or more apertures on one side, and one or more chip stacks joined to the opposite side. Each chip stack includes a flat optics layer (e.g., metasurface), at least one spacer layer, an optional filter layer, and either an image sensor or a light source. In one example, two apertures and two corresponding chip stacks are provided; both chip stacks include image sensors but different metasurfaces and filters to capture different information from the scene. In an alternative embodiment, the two chip stacks include a light source and an image sensor, to function as a light projector and a light receiver, respectively. In other examples, two apertures and a single chip stack are provided, where the single chip stack include two metasurface and/or two filters corresponding to the two apertures.
