Piezoelectroluminescent fiber-optic sensors for temperature and deformation fields

In this research the new designs and algorithms for the piezoelectroluminescent fiber-optic sensors functioning were developed for purposes of diagnosing the distribution of temperature, pressure, and a complex volumetric stress-strain state inside loaded composite structures, based on the results of processing the intensities of integrated monochrome or polychromatic light signals at the output from the optical fiber of the sensor. The results of numerical modeling of the scanning process of an inhomogeneous pressure field by a harmonic wave of the control voltage at the sensor electrodes are also presented. This is only hypothetical sensors, not real sensors yet, although it has great potential to become real sensors. (C) 2019 Elsevier B.V. All rights reserved.
