Comparison of temperature resolution of single-band, dual-band, and multiband infrared systems

A new measure of temperature resolution of IR systems called noise-generated error (NGE) was recently proposed. The NGE does not have limitations of the classical noise-equivalent temperature difference and can be used to describe the resolution of single-band, dual-band, and multiband IR measurement systems. The results of theoretical and experimental testing of the temperature resolution NGE of a developed model of single-band, dual-band, and multiband pyrometers are presented.
