| Outline of Final Research Achievements |
In this subject, we proposed a single-shot complex amplitude measurement method based on transport of intensity equation (TIE), which can acquire amplitude and phase information of moving object. Two intensity object images at different planes in the propagation direction are required for the amplitude and phase information calculation. In general, the optimum distance between these two intensity images is not a constant due to the different dispersion of the object. Therefore, the optimum distance between two intensity images were confirmed by the numerical simulation. Afterwards, to improve the performance of the system, we constructed the experiment setup and tested the system using various samples. We confirmed that the non-uniformity of the wave-front of the beam used for illuminating the object greatly influences the precision of the technique.
