1. A depth imaging system in a vehicle comprising:
a lens including a polarization-coded aperture, the polarization-coded aperture comprising:
a perpendicular polarization portion configured to pass incident light from an object as perpendicularly polarized light;
a parallel polarization portion configured to pass the incident light from the object as parallel polarized light;
an image sensor configured to provide a perpendicularly polarized image of the object at a first location based on the perpendicularly polarized light and a parallel polarized image of the object at a second location based on the parallel polarized light; and
a controller configured to determine a difference between the first location of the perpendicularly polarized image and the second location of the parallel polarized image to determine a range to the object.
