Delta-P1近似漫反射光学模型的二阶参量灵敏度
Sensitivity of Delta-P1 approximation model to second-order parameter
摘要
Abstract
The sensitivity of the second-order parameter "7 of the Henyey-Greenstein phase function based on the spatially-resolved diffuse reflectance within the two-point-source approximation to the Delta-P1 approximation model is studied, and the analytical expression of the sensitivity is derived. The results show that the analytic solution of the Delta-P1 approximation model for reflectance contains the second-order parameter "7 of the scattering phase function compared with the diffusion approximation model, and the second- order parameter "7 has significant influence (the extreme value greater than 30%) on the analytic solution for spatially-resolved diffuse reflectance with small source-detector separations (p 〈 1.5 mm) no matter whether the absorption is weak or strong. The research has theoretical significance for obtaining the optical information abour tissue with the second-order parameter %关键词
