Abstract

Phase distribution detection of cells and tissues is concerned since it is an important auxiliary method for observing biological samples. Here, in this paper, we have proposed phase retrieval algorithms dealing with microscopic interferograms in order to solve two-dimensional phase distribution. Based on phase distributions solved by phase retrieval algorithms, three-dimensional refractive index distribution of biological sample is reconstructed which could reflect inner structure of the cell. We believe these methods could be powerful tools in biological and medical fields.
