Paper Abstract

A new technique has been proposed for deformation measurement by using moments. It is shown that changes in moments enable one to determine the model deformation with high accuracy and sensitivity. The model deformation is also measured by detecting the change in the Fourier transform of the grating printed on the model surface.
