Diffuse light reflectometry for measuring scattering and absorption coefficients of a biological tissue

The optical properties, a scattering and an absorption coefficients, of biological tissues will be used to estimate quantitatively change in bioactivity. Diffuse light reflectometry has been investigated to measure the optical properties of biological tissues from the viewpoints of applicability and practicality. Experimental results obtained from the scattering and the absorption coefficients of the phantom confirm the exactness in measurement by comparing the theoretical values based on the Mie scattering theory. It is also confirmed by changing the roughness of the surface that the performance is effective for the rough surface as a skin tissue.
