Single-shot phase-shifting digital holography is a technique capable of recording three-dimensional (3D) and quantitative phase distributions simultaneously with a single-shot exposure. We have proposed a holographic technique for capturing the information of a 3D structure, phase, temporal change, polarization, and wavelength dependency, which is based on single-shot phase-shifting technique. In this report, we present the basic concept and an optical system for recording motion pictures of wavelength dependency of an object. In the presented system, a monochromatic image sensor captures both a wide-area 3D structure and optical properties of multi-wavelengths with a single-shot exposure. We constructed the optical system and experimented to verify the effectiveness of the presented system. Then, space-bandwidth product for recording the object wave in each wavelength is compared with a conventional off-axis configuration utilizing angular multiplexing technique. |
