Abstract

Recently, relative displacement measurement attracts much attention because of its capability for directly monitoring damages of a building structure. We have developed a noncontact-type relative displacement monitoring system by arranging a two-dimensional PSD paired with a LED array on each story, and investigated the feasibility of this system from the viewpoint of measurement accuracy.
