| Outline of Final Research Achievements |
In this research, (i) the development of an incoherent three-dimensional holographic recording technique and the proposal of a system with high light efficiency, (ii) signal processing techniques for reconstructing a high-quality three-dimensional image, (iii) simultaneous recording of multiple wavelengths with high light efficiency using the technique of (i), and (iv) experimental evaluation of the resolution in digital holographic microscopy were conducted. In (i), the technique was numerically simulated and its validity was confirmed. Also, a novel type of the incoherent system was proposed. In (ii) and (iii), it was clarified that signal processing and multiwavelength imaging techniques can be applied (i). In (iv), it was experimentally demonstrated that digital holographic microscopy has the ability for imaging 775 nm apertures with a single-shot exposure although the experimental evaluation of an incoherent holographic microscope was not experimentally conducted yet.
