Calculation of light scattering of Gaussian beam by spheroidal bubble

The bubble is a part of the particle, and the study of the scattering characteristics of the bubble is of great significance to the optimization of the particle measurement technology. Current light scattering techniques are less efficient for calculating large bubbles. In this paper, the scattering characteristics of ellipsoidal bubbles are studied. The scattering Angle and intensity distribution characteristics of bubbles irradiated by axial Gaussian beams are simulated by geometric optical approximation method. The effects of diffraction, divergence factor and phase shift are considered in the calculation, the influence of Gaussian beam waist radius on scattering intensity distribution is analyzed.
