Image Transmission through Scattering Media Using Ptychographic Iterative Engine

Abstract

Random scattering media prevent light information from directly transmitting through, them as the photons will deviate from their original propagation directions due to the inhomogeneity of the refractive index distribution in scattering media. Based on recent developed methods, light information transmission through scattering media is realized using a memory effect. However, the memory effect range limits it to a small field of view. To enlarge the field of view, in this article, we propose to use the ptychographic iterative engine to deliver information through scattering media. We experimentally demonstrate that the proposed method can deliver images beyond the memory effect range through the scattering layer with outstanding imaging performance.
