    摘要: An optical fiber sensor (5) is disclosed. The optical fiber sensor (5) comprises an optical fiber (20, 220, 520) having an optical microstructure (10, 230, 240, 525) at one end (35, 535); a light source (510) generating coherent light beams for propagation along the optical fiber (20, 220, 520); and a spectrum analyzer (570) for analyzing interference between different ones of the coherent light beams in the optical fiber (20, 220, 520). One of the coherent light beams is adapted to be propagated through the optical microstructure (10, 230, 240, 535) and at least another one of the coherent light beams is adapted as a measuring tool.
