Abstract

PURPOSE: To detect a crack with high speed and high accuracy protecting the damage of a detector by detected materials, controlling the impetus of a detector and the movement toward a detecting point on the basis of a functioning timing signal of a detector and a detecting signal of a displacement of a displacement detector as to the transportation point of a detected material.
