1. An imaging system, comprising:
a laser source;
a digital sensor array;
a processing system including at least one processor, the processing system being configured to perform operations comprising:
transmitting light from the laser source to a target object;
detecting 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, the scattering medium and an image of the target object; and
outputting the jointly estimated image of the target object,
wherein the jointly estimating includes:
determining an intermediate estimate of a transmission matrix of at least one diffuser corresponding to the scattering medium;
for each of a plurality of speckle realizations, inverse propagating wave fields detected at the digital sensor array, back to the estimated diffuser, through the estimated diffuser, and back to a location of the target object;
determining an intermediate estimate of an incoherent object by speckle averaging at a plane of the target object;
determining a performance metric of the estimated incoherent object; and
maximizing the performance metric by iteratively changing the estimate of the transmission matrix.
