1. A system, comprising:
a first polarization volume hologram (PVH) layer configured to deflect a first polarized light having a first handedness;
a second PVH layer coupled to the first PVH layer and configured to deflect a second polarized light having a second handedness opposite to the first handedness; and
an optical sensor configured to generate a first image based on the first polarized light deflected by the first PVH layer, and generate a second image based on the second polarized light deflected by the second PVH layer.

18. A system, comprising:
a first polarization volume hologram (PVH) layer configured to deflect a first polarized light having a first handedness and having a first field of view (FOV); and
a second PVH layer coupled to the first PVH layer and configured to deflect a second polarized light having a second handedness opposite to the first handedness, and having a second FOV,
wherein the first FOV encompasses the second FOV.
