Abstract

A multiband infrared fiber-optic radiometer was developed for online near room temperature and emissivity measurements. Real time measurements were carried out on gray and selective bodies at near room temperature. The mean accuracy obtained for the body temperature was roughly 1°C and for emissivity was roughly 0.03. The radiometer is capable of performing measurements without prior knowledge of the body emissivity. Incorporation of fiber optics allows one to perform measurements without a clear line of sight between the radiometer and the body. This radiometer will have important applications in biology, electronics, and other areas.
