Paper Abstract

The light scattering properties of a transparent spheroidal particle is investigated using defocused interferometric particle imaging. Based on optical transfer matrix theory, the out-of-focus images are simulated using Matlab. We found that the angular variation of a spheroidal particle exhibits isometric with angular variation of the speckle of out-of-focus image. The out-of-focus images of transparent spheroidal particles under different angle of rotation are experimentally acquired using interferometric particle imaging system. The experimental results showed agreement with the simulation results. Thus, we propose a method for obtaining the angular variation of a spheroidal particle using out-of-focus image.
