Japanese sword is Japanese historical famous weapon since ancient times, and has perfectly characteristics as the sharply, strongly influenced by the deformation and broken. Furthermore, the Japanese sword has also an affective characteristics as the traditional crafts, which recognized by the warlords. While the affective shape and historical consideration of Japanese sword is one of the most important variables for evaluating the new generation sword by the modern swordsmith, the Japanese sword have been generally archived by the two-dimensional scanning method. This study aims to try the affective shapely evaluation by three-dimensional archiving of Japanese sword. For the fundamental examination, we designed and manufactured the three-dimensional archiving device by using the stereo digital image correlation method. This paper presents the overview of the manufactured device and the basic measurement results. The goal of this study is to clarify the affective design from the viewpoints of both the shape and the sensual beauty.
Crystallographic analysis of metal cultural heritages is one of important neutron applications, since nondestructive analysis is desired. We have been studying Japanese swords using the pulsed neutron imaging, and obtained position dependent information of crystallite size, anisotropy and lattice spacing. The results coincide with destructive studies, which indicated that the method was useful for the metal artifacts.
