Systems and methods of angle-resolved low coherence interferometry based optical correlation are disclosed. According to an aspect, a method includes directing a sample beam towards a sample for producing a scattered sample beam from the sample. The method also includes receiving the scattered sample beam at a multitude of scattering angles in at least two directions. Further, the method includes cross-correlating the scattered sample beam with a reference beam to produce a two-dimensional angle and depth resolved profile of the sample scattered beam. The method also includes processing the two-dimensional angle and depth scattered profile to obtain correlated information about scattering structures in the sample.
