We propose a visible light coherent diffraction imaging method. The method employs a known standard object as a priori information in the object plane. Illuminating the tested sample and the coalition of the sample and the standard object, respectively, two diffraction patterns can be obtained to reconstruct the complex amplitude of the sample by the proposed iterative algorithm. We show the validity of the method via both numerical simulations and optical experiments. Since only two diffraction patterns are needed to achieve the lensless imaging, our method is simple to implement and has a high application potential.
Key words： complex amplitude imaging; phase retrieval; lensless imaging
