RODRIGUEZ GARCIA, Yoany et al. Development of tapered optical fibers structures (taper), to detect mechanical vibrations. Rev. cienc. tecnol. [online]. 2013, n.19, pp.69-76. ISSN 1851-7587.

A vibration optical fiber sensor based on Tapered single mode fiber and cantilever principles was designed and characterized in this work. The cantilever method used allowed to measure vibrations in industrial equipment induced by mechanical and electrical failure. The device assembled was compared with a commercial accelerometer ISOTRON model 256-100 with a sensitivity of 99.66mV/g, by using an oscilloscope with a Fast Fourier Transformed, in order to compare and analyze the frequency response of the optical fiber sensor. The sensor developed was coupled to an electrical engine, in order to measure the vibrations induced by electrical failure.
