Abstract
A new fibre optic stress/strain sensor, for monitoring hot materials i s reported. The fibre collects grey body emission from a heated materi al sample. When the sample is subjected to transient stresses, the rad iation is modulated due to the adiabatic changes in its temperature. T he modulation is monitored, via a silica fibre, using a near-infrared GaInAs photodetector. This is also believed to be the first demonstrat ion of the SPATE method in the near infrared.
