Overcoming opaque barriers beyond the penetration depth is based on light-matter interactions, with applications in biomedical optics, material science and security. In wave propagation, scattering is the amount of disorder, mostly treated as a disturbance. Scattered light variations allow overcoming opaque barriers. In order to separate turbid medium layers, absorption-based contrast is commonly used. This paper presents the two-layer study of a noninvasive scattering-based technique. The iterative multi-plane optical property extraction (IMOPE) technique assesses scattering by reconstructing the light phase. The reflection-based IMOPE detects different scattering layers with 0.2 mm−1 sensitivity at different depths, behind layers up to 6 mm thick.
