Abstract

The thermal deformation of the plate was measured by phase shifting holographic interferometry. The boundary conditions of the plate are simply supported at two edges and free at two edges. The anticlastic effect is shown in holographic fringe patterns. The strain obtained from the phase shifting holographic interferometry is only slightly different from those from the strain gages.
