Research Abstract	Purpose : It was examined whether the measurement of strain was possible using a recursion reflection of glass beads. Results: That the measurement of strain was possible was checked by measuring a change of the number of glass beads in a constant area. It was confirmed that the measurement of strain was possible precisely by measuring a change of the total area of glass beads in a constant area. The distribution of glass beads is photographed before deformation later and observes the photograph which did layering of the several pieces photographs. And distribution of strain may be observed by the observation of the photograph.
