Abstract

The simple and effective optical arrangement synthesizing holographic fringe and speckle photography is presented. This optical system is based on image holography. Cantilever beam located on the precision translator is used to evaluate this system. Experimental results agree well with the actual displacements within the error of 5%. The measurement of 3-D contact deformation is demonstrated as an its application.
