Reconstructing method of nonlinear dynamic surfaces

In this paper reconstructing method of spherical and variable in time surface based on estimation of the instantaneous values phase with imaginary part of complex white light interferogram logarithm is presented. An accuracy analysis of the above-mentioned method in terms of reconstruction of spherical surface is done here. The methodology of research concerns the synthesis of surface through the mathematical model of interferogram as well as an estimate the error of profile reconstruction. The effectiveness of the method is verified through the reconstruction of surface obtained from interferogram of white light under monitoring the pressure sensor membrane.
