Abstract: |
Scattering phase function is one of the most important optical parameters of medium. In this paper, scattering phase function of different particle radius at different laser wavelengths was calculated by recursive formula of Mie theory and the experiential formula of Wiscombe. On the assumption that non-one particle radius obeying lognormal distribution, scattering phase function at 1.06?mlaser wavelength was calculated, then the result was analyzed simply. Experimental results indicated that the forward and backward scattering peaks of phase function increased when the radius of particle increased. At the same time, when the ratio of the wavelength of incident light to the radius of particle decreased, phase function dithered acutely. In the end, the scattering phase function of non-one particle radius was calculated by Mie theory. The result indicated that the scattering phase function of non-one particle radius dithered more acute than the scattering phase function of one particle radius did, especially for backward scattering.
