Abstract

A method to measure the spectral emissivity and the temperature of selective bodies in the mid and the far infrared (IR) was described using multiband fiber-optic radiometry. A multiband fiber-optic radiometer consisted of a silver halide (AgClBr) infrared transmitting fiber, a dual-band cooled infrared detector, and a set of 18 narrow-band infrared filters, covering the 2-14 μm spectral range. The measurement on the two selective bodies with strong and weak dependence of emissivity was performed as a function of wavelength. It was found that the uncertainties in the spectra of the optical components of the radiometer limit the accuracy of the measured emissivity and the temperature.
