Phase imaging normally employs coherent a light source while an incoherent is not preferred due to its random wavefront. Another challenge for practical phase through scattering media, which scatter the photons in manner and lead seriously distorted images of speckles. Based on convolutional neural network (CNN), this paper presents approach media using source. A CNN was trained utilized recons...

We demonstrate that sub-wavelength optical images borne on partially-spatially-incoherent light can be recovered, from their far-field or from the blurred image, given the prior knowledge that the image is sparse, and only that. The reconstruction method relies on the recently demonstrated sparsity-based sub-wavelength imaging. However, for partially-spatially-incoherent light, the relation bet...
