Paper Abstract

Surface shape and deformation measurement by phase-shifting digital holography using an imaging setup is presented. The differences of the reconstructed phases before and after tilt of the illumination beams and object deformation provide the contour lines of the surface height and deformation, respectively. Suppression of speckle noise and comparisons between experiments and calculation are discussed.
