Outline of Final Research Achievements |
In this project, we developed a calibrated phase-shifting digital holography system by using a single camera. Two types of information were recorded simultaneously in one image based on the space-division-multiplexing in the proposed system. One type of information was used to reconstruct the object image, while the other was used to calculate the phase-shifting amount of the reference beam. By combining the developed system with a microscope, we have successfully recorded the hologram and reconstructed the phase image of the cells which achieved the high precision shape measurement of the cells. A high-precision and high-stability 3D measurement system was realized by this research.
