| Abstract: | The method of measuring direction of mechanical deformation by derence-beam doubleexposure holography is proposed. In the optical system designed, a spread heam is divided into two reference beams and one object beam with the help of the two planar mirrors. Thus the double-exposure interferogram of the measured object under constant deformation can be recorded. Informations of deformation direction are analyzed in theory. The method of using detachable-double-reference-beam double-exposure holography to measure deformation direction is described. Experimental results are given. |
