| Outline of Final Research Achievements |
To implement a technique for recording omni-directional and nano-metre-order precision three-dimensional (3D) image of object with a single image sensor and a single-shot exposure, digital holography systems were studied.
First, a digital holography system based on the technique was designed and constructed for a reflective object. The recording and reconstruction capability of 3D images of both the front and back sides of the reflective object was experimentally confirmed by the system. Next, another digital holography system based on the technique was designed and constructed for a transparent object. This system is based on parallel phase-shifting digital holography using a high-speed polarization imaging camera. To record and reconstruct the 3D image of the internal 3D distribution of refractive index of a transparent object, Abel inversion was employed. Omni-directional 3D imaging of transparent and dynamic gas flow was experimentally demonstrated by the system.
