| Abstract: | The scattering phase functions of the nylon film with different surface roughnesses were measured by the goniophotometric measurement technique, and the corresponding anisotropy factors of the nylon film with different surface roughnesses were determined subsequently. Consequently, the scattering coefficients of nylon with different surface roughnesses were determined. The fluence rates of intralipid with different interface roughnesses for a board beam irradiation were measured and the penetration depths were determined. The experimental results indicate that the surface roughness obviously affects the determination of the optical properties of nylon. This study suggested that the determination of tissue optical properties should take surface roughness into account. |
