Three-dimensional correlation of speckles in deep Fresnel region: extracting the roughness exponent of random surface

We provide a detailed analysis of the three-dimensional cross correlation properties of speckle patterns in the deep Fresnel region scattered by random surface. Basing on Kirchhoff approximation, we first derive the quantitative relationship between the longitudinal correlation function and the frac...
