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.
