Outline of Final Research Achievements

Although the specular reflection component of an object is the same as the light source, it has been reported that specular reflection light of a glossy fabric is chromatic color rather than light source color. The reflection characteristics peculiar to such fabrics are due to the geometric factors of the yarns and the optical factors of the fibers and yarns. Our purpose is investigated the mechanism that specular reflection of the fabric becomes the object color and construct a light reflection model of the fabric. In this study, HDR multiband images of micro level fibers were taken, spectral reflectance characteristics of specular reflection light were estimated, and reflection characteristics of fiber gloss were analyzed. In addition, light propagation inside the fiber was calculated by ray tracing simulation. In addition, we fabricate a fiber structure scaled up with a 3D printer, measure the optical reflection characteristics, and compare it with the measured value.
