摘要
A novel method of phase reconstruction from high-spatial-frequency intensity patterns incorporates the technique of line integration of phase gradient to find the first approximation to the phase and the algorithm of successive approximations to find exactly the unknown phase. The error function is constructed to incorporate the measured intensity to assure rapid convergence.
