Résumé : A new configuration for measuring bubbles with interferometric laser imaging for droplet sizing (ILIDS) is proposed. In this configuration, perpendicularly polarized light scattered by a bubble is gathered at 90°. In this signal, two dominant frequencies are present, whose origin is explained and experimentally verified. Numerical simulations demonstrate how this frequency signature can be used to improve the robustness of the standard ILIDS technique and reject non-spherical bubbles.
