Paper Abstract
A non-interferometric technique for imaging from laser speckle using speckle autocorrelation assisted with sparsity enhanced iterative phase reconstruction is proposed and demonstrated in this paper. The use of sparsity assisted approach in combination with speckle correlation provides the potential to retrieve the complex correlation function from random speckle pattern. Imaging through random scattering medium is demonstrated by recovery of a circular and an annular aperture from the laser speckle.
