Paper Abstract

The optical bi-directional reflectance distribution functions (BRDR) and bi-directional scattering distribution functions (BSDF) of human incisors were measured form -180° to 180° using a scatterometer at 632.8 nm, 1.064 μm, and 3.39 μm. Results from these measurements show that multiple scattering events dominate the optical characteristics of the tooth at the measurement wavelengths in the visible and near-IR. Results form the 3.39 μm wavelength indicate that very little scatter or absorption occurs. This allowed us to obtain an estimated absorption coefficient of about 0.7 cm-1, which is much smaller than previously reported for the visible and near-IR wavelengths.
