建材の表皮•層内における分光反射指向特性の測定

摘要

Highly accurate luminance simulation methods are required to appropriately predict and design various lighting environments. In this study, reflected light from building materials such as PVC floorings, PVC sheets, granite and resin coated metal plates were measured by being separated into the boundary reflection component and the layer reflection component using a polarizer. From the measurement, we obtained a dataset of directional reflection characteristics to be incorporated into luminance simulations. Moreover, the spectral were examined.%(1)ビニル床シート、塩ビシート、花崗岩、樹脂焼付塗装の金属板の仕上げの異なる計19種の建材について、偏光を利用して反射指向特性を層内•表皮反射成分に分けて計測し反射指向特性データを取得した。さらに、以下の傾向を確認した。1)入射角が大きくなるほど表皮反射成分が大きくなりやすい、2)色の違いは層内反射成分との関連がある、3)表面仕上げの違いは表皮反射成分との関連がある。
