Abstract
Under real flow conditions, the critical-angle scattering of a spherical bubble is too noisy to obtain directly the bubble diameter and refractive index. To solve this problem and to limit the drawback of any counting technique, the critical angle refractometry and sizing (CARS) technique has been extended as a collective ensemble technique. As an inverse method it allows to get the size distribution and composition of a cloud of bubbles. In this paper we review the principle, the advantages and limits of this new optical particle characterization method.
