Abstract
Example embodiments provide digital holographic techniques and associated systems for imaging through scattering media in a strictly one-sided observation in which the observer (e.g. the controller of the camera) has no access to the object plane nor does the observer introduce a fluorescing agent to the object plane. An example imaging system comprises a laser source, a digital sensor array, and a processing system. The processing system transmits light from the laser source to a target object; detects interference formed on the digital sensor array by a reference beam from the transmitted light and reflected light from the target object, the reflected light either travelling through or being reflected by a scattering medium located between the target object and the digital sensor array; jointly estimating, based on the detected interference, parameters defining the scattering behavior of the particular scattering medium and an image of the target object; and outputting the jointly estimated scattering parameters and an image of the target object.
