We present experimental results of measurements of light backscattering from semi-infinite disordered media by low-coherence interferometry (LCI). These results are compared with the theory developed in part I [J. Opt. Soc. Am. A 17, 2024 (2000)]. A comparison of the experimental data with the theoretical formulas based on the coherent phase approximation allows us to extract substantial information about the structure of the studied media. Our results demonstrate that LCI is an effective optical technique for studying nonuniform media even in the case in which the dimensions of nonuniformities are much less than the wavelength of the scattered light.
