摘要

In order to describe angular intensity distribution of light in biological tissues, the concept of spatial angular spectrum is introduced in this paper. Light transmitting property in biological tissues can be described by radiative transfer theory, and discrete ordinates method is adopted in solving the radiative transfer equation. A differential equation group is obtained, which can describe the diffuse light field in biological tissues, and its general solutions are also presented in this paper. Based on the general solution, a computer program was designed to calculate the angular spectrum in different biological tissues. And numerical calculates are executed both for isotropic tissues and anisotropic tissues. The results of spatial angular spectrum in biological tissues are illustrated in the form of curves, which illustrates the effects of optical parameters on the angular spectrum in different biological tissues.
