Paper Abstract

The measurement of quasi-static strain field using optical fibers presents a considerable challenge due to the inherent sensitivity of optical fibers to temperature. This paper summarizes recent work we have carried out on two approaches to this problem. Dual mode polarimetric measurements were investigated as a means of implementing distributed temperature measurements and radio frequency subcarrier sensors have been used to perform the same measurement on an integrated basis. These techniques are contrasted and assessed against other technologies such as Bragg gratings and dispersive Fourier transform spectroscopy on the basis of measurement capability, ease of implementation and technological maturity.
