Abstract

We propose a compact and low-cost lensless camera that enables snapshot full-Stokes polarization imaging. Using a polarization-encoded aperture composed of three linear polarizers and a quarter wave plate on a lensless camera, our device can capture 4 images of different linear and circular polarization intensities in a single shot, which can be used to compute full-Stokes images. We can construct an ultra-thin polarization-sensitive lensless camera using a regular image sensor and perform video-rate polarimetry for various applications. We report on the design, construction and imaging performance of our prototype device.
