| Abstract: | Based on the theory of Mie Scattering and its geometrical approximation, a mathematical model for calculation the relationship between the phase differences in Doppler signal and particle size to be measured is established.Several examples for the relationship under common relative refractive indecis are calculated, and the optimum optical arrangement in application is suggested.The results of calculation are compared with what is given by Mie theory.Good agreement is shown. |
