Optical properties of human skin in the near infrared wavelength range of 1000 to 2200 nm

Abstract

In this paper we present the absorption coefficient μ a and the isotropic scattering coefficient μ s ′ for 22 human skin samples measured using a double integrating sphere apparatus in the wavelength range of 1000-2200 nm. These in vitro results show that values for μ a follow 70% of the absorption coefficient of water and values for μ′ s range from 3 to 16 cm -1 . From the measured optical properties, it was found that a 2% Intralipid solution provides a suitable skin tissue phantom.
