Determination of correlation function of scattering potential of quasi-homogeneous medium by Young׳s pinhole configuration

•An approach is presented to determine the correlation function of a QH medium.•Young׳s pinholes produce the incident field with a tunable SDOC.•The correlation function of the medium is obtained from the scattered spectral density.

An approach is presented to determine the correlation function of the scattering potential of a quasi-homogeneous (QH) medium, whereby Young׳s pinholes are employed to block a monochromatic plane wave before scattering upon the medium. Given the following quantities: (i) the spectral density of the incident field; (ii) the on-axis spectral density of the scattered field if one pinhole is blocked; and (iii) the on-axis spectral density if no pinhole is blocked, the approach can be applied to obtain both the strength and the normalized correlation coefficient (NCC) of the scattering potential. Numerical results are displayed to verify the validity of the introduced approach.
