Simultaneous strain and temperature measurement with enhanced intrinsic sensitivity using etched polymer fibre Bragg gratings

Conference Paper


Abstract


  • A PMMA based single-mode polymer optical fibre is etched to different diameter and it is observed that etching can lead to change in the material properties of the fibre such as Young's modulus and thermal expansion coefficient. This can play a vital role in improving the intrinsic sensing capabilities based on etched polymer optical fibre. Thus, exploiting the different strain and temperature sensitivities exhibited by the etched and un-etched polymer FBGs and by using an FBG array, strain and temperature can be measured simultaneously and also with very high sensitivity.
