Abstract An equivalent particle size distribution function n(r) is applied to describe optical scattering property of tissue. Under the Fraunhofer diffraction approximation, both the scattering coefficient μs and the scattering phase function S(θ) are educible from n(r). Moreover, such a scheme provides a new feasible method based on the light scattering techniques for particle size analysis to measure the optical properties of tissue. Experimental results of the whole human blood and a thin porcine muscle sample are also provided and so is a calculation resulting from an optical phantom of tissue. The light scattering equivalency between the practical tissue and the corresponding equivalent particles has been verified.
