Passive Near-Infrared 3D Sensing and Computational Reconstruction With Synthetic Aperture Integral Imaging

We present near-infrared (NIR) 3D sensing and reconstruction of occluded objects using synthetic aperture integral imaging (SAII). We present experiments with the NIR 3D imaging system using a radiant object. The occluded object is not observed in visible spectrum due to front obstruction. However, with 3D computational reconstruction, the NIR image of the object shows substantially reduced front obstruction. To the best of our knowledge, this is the first report on NIR 3D reconstruction of occluded objects using SAII.
