Optical fiber sensor based on the excitation of surface plasma.

摘要

Optical fiber sensor based on the excitation of surface plasma comprised of a sensor head (1) formed by a transparent body (5) with a flat surface (7) that incorporates a thin metal layer (9), on which the optical excitation of surface plasma is produced, a second mirrored cylindric surface (6) perpendicular to the anterior one and another flat one (10) forming with the first one an PHI angle, which is determined by the refraction indexes of the transparent body and of the medium to be controlled and two optical fibers (12) and (13.)
