Paper Abstract

A method though the combination of a phase array plate and linear interpolation has been used to substitute phase-shifting, where effect of nonlinear interpolation is neglected. In this paper we mainly study the effect of non-linear interpolation in a phase array plate. The results of reconstructed image under several nonlinear interpolations such as cubic and nearest interpolations are given and are compared with those of linear interpolation and standard interpolation. Because only one hologram is needed in our method, it can be used in real-time measurement of a moving object.
