Novel fibre optic stress/strain sensor, using the near-infrared SPATE effect (FONI-SPATE)
Novel fibre optic stress/strain sensor, using the near-infrared SPATE effect (FONI-SPATE)
A new fiber optic stress/strain sensor, utilizing near-infrared SPATE, is reported which is suitable for monitoring hot materials. The fiber is merely arranged to collect the grey body emission from a heated metal sample. When the sample is subject to transient stresses, the radiation is modulated because of the adiabatic changes in the temperature of the material surface. The modulation of the light is monitored, via a silica optical fiber, using a near-infrared GaInAs photo-detector. This is also believed to be the first demonstration of SPATE in the near infrared region of the spectrum.

Abstract
A new fiber optic stress/strain sensor, utilizing near-infrared SPATE, is reported which is suitable for monitoring hot materials. The fiber is merely arranged to collect the grey body emission from a heated metal sample. When the sample is subject to transient stresses, the radiation is modulated because of the adiabatic changes in the temperature of the material surface. The modulation of the light is monitored, via a silica optical fiber, using a near-infrared GaInAs photo-detector. This is also believed to be the first demonstration of SPATE in the near infrared region of the spectrum.
