Paper Abstract

A simple spatial filtering is added in moire deflectometry (MD) which raises the sensitivity, improves the contrast of moire patterns, and makes the viewing plate conjugate to the phase objects under test. This modified system is called moire interferometer (MI). Using the Fourier method, this paper analyzes the measurement principle of MI and obtains a strict relationship between a tested wave function and the shift of moire fringes.
