    Using polarization cameras for snapshot imaging of phase, depth, and spectrum

    By encoding object information (object phase, surface height, spectrum) into the polarization state, we can use polarization cameras to image other dimensions of the light field while viewing dynamic scenes. W...

    Aerial video-calling system with eye-matching feature based on polarization-modulated aerial imaging by retro-reflection (p-AIRR)

    We propose a method to realize video calling with an aerial display using a camera that has a direct view of the speaker's face, but which is not visible to the speaker. Because the aerial display uses p-AIRR ...

    Birefringence compensation for single-shot 3D profilometry using a full-Stokes imaging polarimeter

    We demonstrate a single-shot uniaxial 3D profilometry system that illuminates a sample with a structured polarization pattern and measures the reflected full-Stokes polarimetric image. Some non-contact 3D meas...

    Implementation of a complete Mueller matrix polarimeter using dual photoelastic modulators and rotating wave plates

    We propose a complete Mueller matrix polarimeter using dual photoelastic modulators and rotating half wave plates. The complete Mueller matrix of a sample is obtained by combining four partial Mueller matrices...
