This paper presents the application and comparison of a macrobend seismic optical fiber accelerometer and ferrule-top cantilever fiber sensor (made by Optics11 - Amsterdam, Netherlands) both for long distance vibration monitoring. The sensors utilize typical telecommunication optical transmission systems with specially prepared sensing head. Both optical fiber sensors measure force and acceleration similar to the piezoelectric accelerometers. One of the advantages of these devices is insensitivity to electromagnetic interference because of lack of electrically driven elements in sensing head area. Experiments with wide ranges of frequencies and vibration amplitudes were performed. Main parameters and measurement capabilities of both sensor types were compared. Experimental results show usage possibility of both sensor types in industry and other explosion risk environments for vibration measurement and online monitoring.

Composite structures are made of two or more components with significantly different physical or chemical properties and they remain separate and distinct in a macroscopic level within the finished structure. This feature allows for introducing optical fiber sensors into the composite material. These sensors can demonstrate stress distribution inside tested material influenced by external tensions. Two types of the optical fiber sensors are used as the 3D structure. One of them is based on application of fiber Bragg grating inside the core of the fiber. Longitudinal stress changes parameters of the Bragg grating and simultaneously, spectral characteristics of the light transmitted through the fiber. The second one is based on application of highly birefringent fibers which, under external stress, introduce polarization changes of the output light.
