Device for the discrimination of fluids having different indices, and device for the measurement of the volume fraction of at least one fluid in a stream of non-miscible fluids, using the same device

摘要

The device consists of an optical fibre coupler (4) with at least three ends (5 to 8). Connected to the ends are a semiconductor light source (1) whose intensity is modulated, a photoconducting semiconductor (2) and an optical sensor consisting of a multimode optical fibre (3) with a pointed end. …IMAGE…
