SYSTEM AND METHOD FOR RECONSTRUCTION OF HOLOGRAPHIC LENS-FREE IMAGES BY MULTI-DEPTH SPARSE PHASE RECOVERY

摘要

A system for lens-free imaging includes a processor in communication with a lens-free image sensor. The processor is programmed to operate the image sensor to obtain a hologram ??. The processor is further programmed to generate, from the hologram, a reconstructed image X and phase W at a focal depth z using an assumption of sparsity.
