Special Issue Information

Dear Colleagues,

The monitoring of structures, especially civil engineering structures and infrastructures, has a huge impact at the social and economic level. The study of its performance in different buildings began in the late 20th century, and its development has increased considerably in the last years, resulting in the implementation of numerous prototypes in existent structures.

The monitoring and identification of potential structural damage and its evolution requires the development of advanced structural sensing networks and monitoring techniques. Within the detection technologies, optical fiber sensors (OFS) present advantages over several other technologies. Recent advances in the field of optoelectronics have increased and highlighted the importance of OFS in relation to electrical devices. These have valuable features such as immunity to electromagnetic interference, high sensitivity and resolution, multiplexing capabilities, absence of electrical power in the measurement area, reduced size and mass, resistance to extreme environments (chemicals), and minimal aesthetic invasion (important for historic structures open to the public).

This Special Issue will present and discuss all types of OFS with potential use in structural monitoring. The manuscripts should cover, but are not limited to, the following topics:

  • Low-cost, miniaturized, selective, and multiparameter optical devices;
  • SHM case studies using optical fiber technologies;
  • OFS for physical, chemical, and environmental SHM;
  • Fiber interferometric and polarimetric sensors;
  • Nano- and micro-structured and photonic crystal fiber sensors;
  • OFS Multiplexing and sensor networking;
  • Distributed sensing;
  • Advances in interrogation techniques for optical sensing;
  • Smart structures and sensors;
  • Bragg gratings, Fabry Perot cavities, plasmonic and Mach Zehnder interferometers;
  • Damage detection algorithms and characterization using optical fiber technologies.

The results of strain measuring experiments, with the help of rosettes consisting of fiber Bragg grating sensors (FBG) embedded at the manufacturing stage in a polymer composite material are considered in this paper. The samples were made by the direct pressing method from fiberglass prepregs. A cross-shaped sample was tested under loading conditions corresponding to a complex stress state. A variant of strain calculations based on experimental data is discussed. The calculations were performed under the assumption of a uniaxial stress state in an optical fiber embedded in the material. The obtained results provide a reasonable explanation of the absence in the conducted experiment of two peaks in the reflected optical spectrum, the presence of which follows from the known theoretical principles. The experimental result with two peaks in the reflected optical spectrum was obtained for the same sample under a different loading scheme. The proposed variant of the numerical model of the experiment and the results of numerical simulation made for FBG rosettes embedded in the material allowed to estimate error in the strain values calculated on the assumption of the uniaxial stress state in the optical fiber and in the presence of two peaks in the reflected optical spectrum.
