| Outline of Final Research Achievements |
In surface modification, to improve the functionality of a material surface, fine processing called "surface texture" on the surface of the material is often performed. On the other hand, light reflection from an object depends on the material and micro-structure of the object's surface. We have proposed a simple measurement method for obtaining reflection characteristics using a fisheye camera. In this study, as a first step to estimate the functionality of the surface texture from the surface characteristic, by using a fish-eye camera system, we measure the reflection properties of the surface texture that is processed simple irregularities repeatedly. Then, we consider the correlation between the reflection characteristics and the periodicity of the surface texture.
