| Outline of Final Research Achievements |
The measurement and control of light waves have been long studied as a fundamental technology across a wide range of fields such as life sciences, material science, and entertainment, with various methods being developed. However, the trade-off between the cost of optical systems and imaging performance has been a challenge. In this research, we actively utilized information science technology, which has seen remarkable development in recent years, exemplified by deep learning, to develop modulating elements for the high functionality and cost reduction of light wave imaging. Specifically, we worked on developing a holographic display with new functions, light wave microscopy, diffractive optical elements for wide-field imaging, and scatter imaging.
