摘要：
In this paper, a new practical technique is presented based on digital holography, for the reconstruction of a wave front from three intensity recordings. Combining the off-axis Fourier filtering technique with boundary detection and iterative phase retrieval algorithms, it is shown how problems such as elimination of the twin image can be overcome. The proposed methods deal with also the issues of feasibility and accuracy associated with off-axis Fourier spatial filtering (OFSF), and those of cost and alignment associated with phase shifting interferometry (PSI). Problems associated with working with diffuse objects are also overcome.
