Optimized Denoising Method for Fourier Ptychographic Microscopy Based on Wirtinger Flow

Fourier ptychographic microscopy (FPM) is a recently developed technique for high-resolution complex imaging with a wide field-of-view. FPM combines captured low-resolution images corresponding to angle-varying illuminations in the Fourier domain with phase retrieval and synthetic aperture algorithms; consequently, it can surpass the space-bandwidth product limit of an objective lens. In typical F...
