Paper Abstract

The weak absorption of near-IR light by skin tissue has offered an important optical window for diagnostic possibilities with optical means including optical biopsy. The strong scattering of the near-IR light by skin tissue, however, presents a great challenge to the modeling of light propagation through and the optical measurement of the tissue. We have measured transmittance and reflectance of fresh porcine skin and performed Monte Carlo simulations to inversely determine the absorption coefficient, scattering coefficient and asymmetric coefficient of tissue samples in the spectral range from 900 to 1500nm. The state of cellular integrity following optical measurements was verified using transmission electron microscopy. These results were correlated with the possible effects on the measurements of the tissue optical properties.
