METHOD OF MEASURING TEMPERATURE

摘要

A method is proposed of measuring the temperature (T) of objects with unknown radiating capacity on the basis of their own radiation. The method involves the following steps: gathering and focusing of the radiation; selection of N spectral bands, conversion of the radiation in every i-th spectral band into an electrical signal, and amplification thereof; introduction of two pairs of linear combinations of the signals obtained from N spectral bands, and calculation of a ratio. The parameters of the linear combinations are selected so as to ensure that the ratio: first linear combination / second linear combination is equal to the absolute value of the measured temperature
