Paper Abstract

Observations were made of the near backward scattering of polarized laser light from freely rising spherical and oblate spheroidal air bubbles in fresh water. The cross-polarized pattern was observed and was modeled with a physical optics approximation for two different incident polarization directions relative to the axis of rotational symmetry of the spheroidal bubble. A rigid sphere drag law and relations from hydrodynamics were used to estimate bubble oblateness. The directional caustics associated with the near-backward directed wavefronts from oblate bubbles were calculated and may be used to estimate bubble oblateness from certain features of the angular scattering pattern.
