Abstract
Biological tissues produce high levels of optical scattering in the visible and near-infrared. A phase function is often used to characterize the scattering properties of the media. Henyey- Greenstein's phase function has been widely adopted by researchers in the biomedical optics field. A new scattering phase function is proposed to approximate phase functions strictly derived from Mie scattering theory. The new phase function demonstrates much better agreement with Mie theory than Henyey-Greenstein's phase function. In calculation of light propagation within biological media using the radiative transport equation, the phase function plays an even more important role. Using the new phase function as the integral kernel in the radiative transport equation, an analytical expression for the integral term of the equation is obtained for highly aligned beams. This may lead to a semi-analytical solution to the time- dependent radiative transport equation for time-resolved spectroscopy.
