Abstract
We report a novel wide-field lens-free 3D microscopy, which is based on Fourier ptychography diffraction tomography (FPDT) technique. This method uses only one illumination angle to obtain a large enough number of diffractograms by scanning a wide range of wavelengths, applying an iterative method to fill the 3D spectrum, and finally recovering the refractive index (RI) distribution of the sample. And the effectiveness of the method in the 3D RI distribution reconstruction of a tilted phase target is experimentally verified.
