赤外放射を利用する温度測定

After a brief survey of the possibilities of obtaining informations about temperature by means of infrared radiation, proposed is a classification of realizable methods into three schemes; the equilibrium scheme, the active scheme and the passive scheme. Among others the pas-sive scheme, which covers the so-called radiation thermometry, is discussed in detail; the factors causing the degradation of information along the path of radiation, namely the effective emis-sivity of the radiation source, the absorption and the scattering of radiation in the atmospheric path as well as the performances of the detecting devices, are examined. Finally reviewed are various examples of success and trial which seem to be instructive in view of improving the quality of information about temperature transmitted by infrared radiation.
