Properties of Phase Functions for Biological Materials with Properties of Composite Materials and their High-Order Parameters
Biological materials with properties of composite materials are complex, phase function can describe the complexity. Several phase functions and their high-order parameters were discussed. The results demonstrate that: single HG(Henyey-Greenstein) phase function can not describe the scattering of real biological material, the high-order parameters are dependent on the first-order parameter; Mie phase function can provide theorical reference for scattering chart of biological material although the function is complex;Tissue phase function can picture scattering for most biological materials and the form is simpleness, the high-order parameters are independent and relate to the micro-structures of biological material. it is necessary of selecting appropriate phase function for applied technology of medical diagnosis and measurement of optical parameters.
