Characterization of Two-Layer Diffuse Media by Reflection of Gigahertz Photon Density Waves.

摘要

Diffuse reflected light is used to characterize optical properties of two-layer turbid media. The source is modulated in gigahertz frequencies. The phase and amplitude of analytical reflectance is fitted to the data generated by adding 2.5% noise in amplitude and 1 degree noise in phase to the solution of diffusion approximation in gigahertz frequency regime. The extracted optical properties are in good agreement with the real values.
