A Lensless Polarization Camera

ArXi:2603.17156v1 Announce Type: cross Polarization imaging is a technique that creates a pixel map of the polarization state in a scene. Although invisible to the human eye, polarization can assist various sensing and computer vision tasks. Existing polarization cameras use spatial or temporal multiplexing, which increases the camera volume, weight, cost, or all of the above. Recent lensless imaging approaches, such as DiffuserCam, have nstrated that compact imaging systems can be realized by replacing the lens with a coding element and performing computational reconstruction.
