Abstract
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.

In light-matter interaction, the scattering ability of a medium is the quantification of its micro- and macro-structure
The iterative multi-plane optical property extraction (IMOPE) technique extracts the scattering properties of a medium based on the reemitted light phase, which is reconstructed by the GS algorithm

Summary
In light-matter interaction, the scattering ability of a medium is the quantification of its micro- and macro-structure. Using the forward model of photon propagation and image reconstruction algorithms, DOT provides a spatial map of the optical properties of thick tissues. Though, it somewhat suffers from a low spatial resolution, it has been applied for breast cancer diagnosis [4]–[6] and brain functional imaging [7]–[9]. It somewhat suffers from a low spatial resolution, it has been applied for breast cancer diagnosis [4]–[6] and brain functional imaging [7]–[9] Another technique is photoacoustic tomography (PAT) [10], which combines acoustic detection and optical absorption to create high-resolution images. Using the multiple scattered light, as well as the ballistic photons, provides imaging of layers deep
