Introduction of Sangkan imaging and phase recovery algorithm (i.)

This paper mainly introduces Sangkan imaging (coherent diffractive IMAGING,CDI), and the various phase recovery algorithms used in it, including geometrical optics, Fourier optics, functional, optimization theory. The code is published in two ways, MATLAB and OpenCV.

Matlab code is my work in the past few years, mainly to rewrite into OPENCV version of the Code, practice practiced hand, learning under OPENCV. In addition, know on-line about phase recovery of valuable papers less, however, foreign this thing has been done all over the street, so think of an introduction and introduction of the role.

Sangkan Imaging Technology The word is: use complex software instead of complex hardware.

The computing power and computational cost of computers are getting lower and higher, which can make many problems solved by hardware instead of software. So the key to Sangkan imaging is software and algorithms.

Sangkan Imaging lost the phase information of light, only retained the amplitude information, so to restore the phase information to smooth imaging, so there is a phase recovery problem in Sangkan imaging, need to have a phase recovery algorithm.

The following describes the traditional imaging principle and the principle of Sangkan imaging technology:
