Abstract
Disclosed herein is various shared-aperture camera systems and calibration methods. One particular shared-aperture camera system includes a polarization imaging device including: an aperture; a first metasurface configured to diffract incident light going through the aperture such that a first polarization of incident light diffracts in a first direction and a second polarization of the incident light diffracts in a second direction; an image sensor; and a planar diffractive lens including a second metasurface configured to focus the first polarization of incident light diffracted in the first direction onto a first portion of the image sensor and focus the second polarization of incident light diffracted in the second direction onto a second portion of the image sensor.
