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