要約(英語): An object's optical reflection properties are due to the microscopic structure of the object's surface. Therefore, optical reflection measurement is important to obtain a realistic representation in computer graphics and in the inspection of industrial parts. In this study, we developed a compact reflectance measurement system without a mechanical drive unit. The system has the advantage of being simple and highly portable compared to the conventional measuring device used for this purpose. We constructed a prototype camera system and carried out several experiments to test it. The experimental results showed that the reflection characteristics will vary depending on the surface roughness of objects, and we could recognize the state of the surface reflection visually.
