Abstract

Single integrating sphere technique was used to measure respectively total reflectance and transmittance of porcine nasopharynx tissue under the irradiation of He-Ne laser with the wavelength of 632.8nm, which has the advantage over conventional double-sphere techniques in that no corrections are required for sphere properties. In addition, with the measurement of unscattered transmission, the optical properties of porcine nasopharynx tissue in vitro have been determined by using Inverse Adding-Doubling Method. The optical properties of porcine nasopharynx tissue are characterized by low absorption (0.096mm-1) and high scatter (6.27mm-1). The scattered light is highly forward as demonstrated by the mean cosine of the scattering angle (0.92), and the optical penetration depth for porcine nasopharynx tissue at the wavelength of 632.8nm is about 2.4 1mm.
