Abstract

Optical imaging through diffusive or scattering media has attracted much attention. Digital holographic microscopy provides quantitative phase imaging thorough diffusive media. We experimentally reconstruct intensity and phase images of an object through an opaque ground glass screen by means of digital holography. A clear image of the object is acquired by wavefield back propagation algorithm for the object with an information of a quantitative phase distribution of the diffusive screen measured in advance with the principle of the lensless digital holography.
