Notes:
Standard radiometric thermometry is based on measuring the infrared radiation emitted from a body in one broad spectral band. However, the "true" temperature, Tbody, can not be determined accurately if the emissivity, cursive-epsilon, and the ambient temperature, Troom, are not known or change during the measurement. We constructed a "four band" fiber-optic radiometer for measurement of Tbody near room temperature, where measurements of the emitted radiation were carried out in four spectral bands. The radiometer was analyzed theoretically, and was then calibrated and tested on black and gray bodies. Good correlation between theory and experiment was achieved. © 2000 American Institute of Physics.
