Demultiplexing multiview images from a single-shot speckle pattern with scattering media (Conference Presentation)

Paper Abstract

In this paper, we present a single-shot multiview imaging technique for three-dimensional objects by utilizing the nature randomness of scattering media. The uncorrelated point spread functions of different scattering regions help to de-multiplex multiple elemental images at different viewing angles by deconvolution from only a single speckle pattern. Our demonstration shows that not only stereo capture with large disparity, but also, up to 7 viewing angles of a 3D object can be reconstructed with just a single shot, if corresponding PSFs are premeasured once. The elemental images are consistent with 3D object projection and images taken by multi-shot imaging.
