Phase Information Recovery Using Noninterference Technology

In this chapter, the detailed derivation of the strength transfer equation (TIE) is first described. Secondly, several different methods to solve the TIE equation are given, such as Fourier method, multigrid method, etc. On the basis of previous studies, we focus on the Fourier method. This paper also gives the specific derivation of the method and briefly discusses the correctness of this method. Finally, this paper uses Fourier algorithm to do a series of simulation experiments of different images at different distances, and makes a brief analysis of the experimental results. Moreover, two sets of real pictures were taken by laboratory CCD, and corresponding real experiments were carried out, which confirmed the feasibility and practicability of the algorithm, and the experimental results were briefly analyzed.
