Abstract (en)
[origin: WO2009138634A1] The invention relates to an optical probe comprising an optical fibre (51) associated with a conical tip (7), made of sapphire or diamond, with a circular base (71) and having, between the base and the end, an annular groove (73) with a curved bottom (731) or at least one axisymmetric shoulder. The invention also relates to a method and a system for determining characteristic quantities of a two-phase flow using such a probe.
