| مستخلص: | Objective: This study aims to correlate human skin phototypes with complete optical characterization (absorption, scattering, effective attenuation, optical penetration, and albedo coefficients) based on individual typology angle (ITA) values and colorimetric parameters. Methods: A colorimeter was used to group 12, fresh, ex vivo human skin samples according to their phototype; the CIELAB color scale and ITA values were employed. An integrating sphere system and the inverse adding-doubling algorithm were applied during optical characterization, conducted from 500 to 1300 nm. Results: On the basis of ITA values and their classification, the skin samples were separated into six groups: two intermediates, two tan, and two brown. In the visible range, for lower ITA values (darker skins), the absorption and effective attenuation coefficient parameters increased, whereas the albedo and depth penetration parameters decreased. In the infrared region, all the phototypes had similar parameters. The scattering coefficient was similar for all the samples and did not change with ITA values. Conclusions: ITA analysis, a quantitative method, showed that the human skin tissue's optical properties and pigmentation colors were highly correlated. |
