In this paper, we propose three-dimensional (3-D) holographic sensing, and computational/optical 3-D integral imaging reconstruction. We demonstrate experimentally that through the integral imaging technique, it is possible to reconstruct a full 3-D scene which has been obtained by digital holograms. Three-dimensional color objects can also be displayed optically in 3-D without convergence-accommodation conflict using a microlens array, and a two-dimensional (2-D) display panel illuminated by incoherent light. The proposed approach takes advantages of high resolution holographic sensing and robust 3-D integral imaging visualization.
