Palm-sized single-shot phase-shifting incoherent digital holography system
Tatsuki Tahara, Ryutaro Oi
Abstract
We propose a palm-sized single-shot phase-shifting incoherent digital holography (SSPS-IDH) system in which three-dimensional (3D) information of spatially incoherent light is recorded as a self-interference hologram. To implement this single-shot 3D recording system, we adopt thin optical elements and no refractive lens. 3D information is obtained with a single-shot exposure of a polarization image sensor. More than 3,800-fold downsizing in volume can be achieved in comparison with a conventional incoherent digital holography (DH) system. An SSPS-IDH system is constructed, and its single-shot 3D sensing ability is experimentally demonstrated.
