Spatially Resolved Diffuse Reflectance Measurements of Two-layered Samples in the Frequency Domain

Spatially resolved diffuse reflectance measurements of two layer tissue phantoms were performed in the frequency domain. The non-invasive surface technique can differentiate between homogeneous and layered media. The measurements of the layered phantoms are compared to a diffusion theory model for layered media. It is found that the technique is sensitive to the optical properties of each layer.
