Abstract
Disclosed is an interferometric fiber optic sensor for detecting chemical substances. A light source a detector are connected to a light dividing element in an optical path with an optical fiber segment. The optical fiber segment is further optically coupled with a measuring element across a residual cavity. The measuring element further has a face adapted to be exposed to a test substance that may contain a chemical substance to be detected. The optical fiber segment and the measuring element can be held together so that there is only the residual cavity between them. The optical fiber segment is contained, at least along part of its length, within a capillary. A first end part of the capillary is joined with the measuring element while another portion of the capillary is joined or clenched on the optical fiber segment, so that the capillary, the optical fiber segment and the measuring element together form a fiber optic measuring probe as a part of the optical path with the light source and detector.
