A new efficient and accurate method which identifies phase distribution of coherent light from its modulated intensity images has been developed. This method is summarized as the following. 1)The identification problem reduced to the non linear optimization problem whose design valuables are the Zernike coefficients. 2)Fast Fourier Transform was applied to the large scale matrix calculation, in order to decrease the computational time. 3)The matrix which represents the coherent light propagation is accurately modeled with boundary element method. 4) A numerical example problem is solved to demonstrate the effectiveness of the present method. 5) Practical experiment was performed, and the phase distribution could be identified from real data within two seconds.
