| Abstract(J) | NIR後方散乱画像による凍結路面μの計測においては，氷表面およびその下層である路面層からの反射が複合された多層反射を計測しており，特に，路面層からの反射光は測定波長と表面粗さの両方に依存すると考えられる．本研究ではこれらの反射特性について調査し，後方散乱光による凍結路面μ計測の妥当性について理論的に検証した． Translation |
| Abstract(E) | In the measurement of the friction coefficient (μ) of icy road surfaces using NIR backscattered images, multilayer reflections composed of reflections from both the ice surface and the underlying road surface layer are measured. In particular, the reflected light from the road surface layer is considered to depend on both the measurement wavelength and the surface roughness. In this study, these reflection characteristics were investigated, and the validity of measuring the friction coefficient (μ) of icy road surfaces using backscattered light was theoretically verified. |
