| Outline of Final Research Achievements |
The purpose of this research is to realize optical techniques to investigate the moisture situation of crops in the plant factory, including microscopy, hyperspectral imaging, and spectroscopy. One-shot and full-field confocal microscope has been realized by use of 2D spectral coding and dual-comb spectroscopy. A novel 3D illumination by use of retro-reflector has been developed to converge the illumination light inside a group of leaves. Furthermore, we developed a handheld, scissors-like, spectroscopic sensing apparatus that evaluates water content in a crop leave by sandwiching the leave.
