PCT No. PCT/FR84/00106 Sec. 371 Date Dec. 24, 1984 Sec. 102(e) Date Dec. 24, 1984 PCT Filed Apr. 16, 1984 PCT Pub. No. WO84/04384 PCT Pub. Date Nov. 8, 1984.The invention relates to an optical probe comprising an optical means (5) having a given refractive index. This optical means is able to reflect an incident light beam if it is located in a medium (3), whose refractive index is higher than the given index and is able to reflect the incident light beam if it is in a medium (2), whose index is below the given index. The optical refraction or reflection means (5) is a cone of revolution, the axis (X) thereof being parallel to the incident beam (6) and to the optionally reflected beam (11), the base (12) of said cone receiving the incident light beam and is perpendicular to said incident light beam and to the possibly refracted beam. The cone and at least part of the optical fibres transmitting the incident and reflected light beams are located in a tight box or case. Application to the detection of interfaces of different media and to the determination of the components of a two-phase medium. |
