Many phenomena take place during different types of emulsion inversions, particularly a change in interface curvature and drop size, which could be detected by backward light scattering. Monitoring the backscattering signal allows us to detect the emulsion inversion in three main cases, one transitional and two catastrophic types. The backscattering data could give some clue as to emulsion morphology, which is not available from conductivity measurements.
