Abstract
Systems and methods for simultaneous focal length control and achromatic computational imaging with quartic metasurfaces are disclosed herein. In one embodiment, an imaging system includes: a first metalens having a plurality of first nanoposts carried by a first substrate; a second metalens having a plurality of second nanoposts carried by a second substrate; and a source of light configured to emit light toward the first metalens and the second metalens. The first metalens is transversely offset with respect to the second metalens.
