I am trying to find a way to measure the temperature of optical fiber.
I have a thermocouple (mechanically contacted) and FLIR thermal
camera.
It seems that two are giving a large differnece on measurement.
I am trying to figure out if there is something i did wrong. Or if
there is any fundamental limit.
Thermal cameras (unless they are spectrometers) rely on guessing the
spectral distribution of the recieved IR light correctly. Although for many
materials assuming a black-body spectrum -or whatever the camera assumes- is
a reasonable guess this might be and probably is quite wrong for an optical
fiber. Thus I would only trust the thermocouple. You should be able to use
the thermocouple data to calibrate your camera to the spectrum emitted by
the fiber.
Cheers,
