Paper Abstract

A precise interferometric method for three-dimensional shape measurements in a wide dynamic range with double symmetrical illumination of the objects is presented. The technique proposed is especially useful for remote, non-destructive in-situ measurements of art and archaeological objects. The method is based on projection two-spacing phase-stepping interferometry. The theoretical approach, experimental results as well as a sensitivity assessment of the measurements are discussed.
