Paper Abstract

Lens-Free microscopy aims at recovering an observed object such as cell cultures from its diffraction measurements. Diffraction acquisitions are processed with an inverse problem approach to recover optical path difference (OPD) images of the object. Phase unwrapping issue is solved here by using a convolutional neural network (CNN) trained on simulations. The procedure was applied successfully on a neuron cells culture video acquisition.
