Abstract

A new calculation method for a quadrature phase-shifting interferometer is presented and its application to digital holography is also described. Two sets of quadrature phase-shifed interferograms or holograms are acquired and the new calculation method proposed gives the phase distribution of the wavefront measured. The principle of the calculation method with computer simulations and its application to digital holography with experimental results are given.
