| Research Abstract |
We established the quantitative technique to visualize the shape and structure of biological tissue which has a small difference of a refractive index. We were able to get the sub-wavelength phase distribution as depth by using the phase modulation differential interference microscope which we developed. Moreover, when we observe three-dimensional object there was a problem which disturbs reconstruction with blurred image before and behind an exact image plane. Consequently, we combined the Nearest Neighbor Deblurring method with the phase reconstruction technique of a phase modulation differential interference microscope, and confirmed its availability.
