Abstract
A polarization-sensitive imager, include a polarization filter, the polarization filter including a first region and a second region, a pixel array of light sensors coupled to the polarization filter, the pixel array of light sensors including a first region associated with the first region of the polarization filter and a second region associated with the second region of the polarization filter, each region of the pixel array of light sensors configured to output a signal based on an amount of light illuminated on the region and a processor configured to simultaneously determine an intensity image and a polarization image by taking a sum and difference of the signal of the first region of the pixel array of lights sensors and the signal of the second region of the pixel array of light sensors.
