Abstract

The study on trichromatic optical fiber radiation thermometers is especially useful for the non- contact accurate temperature measurement of those materials with the emissivities changing dramatically with wavelength. On the basis of the trichromatic thermometry principle, the operation wavelengths of the thermometer are selected properly so as to compensate the emissivity's influence on measurement result effectively. Using 1 X 3 branching fiber coupler and narrow band filter significantly improves the instrument's reliability. The instrument is self-calibrated, multi-functional and easy to use due to the embodied microcontroller and some other techniques.
