| Outline of Final Research Achievements |
In this study, laser speckle analysis that uses light with strong interference was developed to obtain the information of plant physiology such as response to stress. We proposed a laser speckle method using polarized light and could detect plant responses to water stress at an early stage. This proposed method could evaluate plant surface and inner structure with a single speckle image and would be suitable for usage on the field.

本研究成果は，1枚のスペックル画像の解析による容易さと，偏光を利用することで複雑な植物体構造を分離できかつ，先駆的現象として現れる内部構造変化を早期に評価できる特徴を持つ．既存の植物生理情報では，内容成分やその濃度に依存した計測が実施されてきたが，本解析では植物体の構造に着目した生理情報であり，これまでの植物生理情報とは異なり，構造に依存する受光効率やガス交換効率などの新たな植物生理情報を非破壊で評価できる可能性がある．
