Abstract: Systems and techniques for polarization are illustrated. One embodiment includes a system for polarization imaging. The system includes a camera that is an autofocus sensor. The camera includes a main lens. An aperture plane of the main lens is overlaid with a multiplexed polarization filter, where the multiplexed polarization filter includes a plurality of sub-filters; and each sub-filter follows a distinct polarization angle. The camera includes a detector array, wherein the detector array includes a plurality of sensor pixels. The camera includes a microlens array including a plurality of microlenses overlaid over the detector array. The microlens array is placed at a focal plane of the main lens. Each microlens is: unfiltered; and configured to direct incident light to a distinct subset of the sensor pixels. The system further includes a memory storing image data and a processor configured to execute instructions to process the image data.
