| Outline of Final Research Achievements |
I developed optical systems that acquire holographic three-dimensional images at visible and near-infrared wavelengths simultaneously and succeeded in observing a paramecium swimming freely in water with the systems. Then, I improved the resolution in multi-wavelength digital holography by using the signal theory, and phase-shifting interferometry selectively extracting wavelength information that had been proposed initially on 2013. The constructed multi-color digital holographic microscopy based on the phase-shifting interferometry performed color three-dimensional imaging of a biological specimen that had a 1um-order structure. Acquisition of polarization information with digital holography was also confirmed. From the results described above, the developments of elemental technologies were successfully achieved and a multi-spectral, polarization-imaging, and three-dimensional motion-picture digital holographic microscopy system is constructed.
