RADIOMETRIC TEMPERATURE MEASURING METHOD AND RADIOMETRIC TEMPERATURE MEASURING SYSTEM

摘要

Disclosed are a radiometric temperature measuring method and a radiometric temperature measuring system (10). A thin film (2) is formed on a substrate (1). The polarized radiation luminance component emitted from the thin film (2) is measured in a range of angle ϑeic where the emissivity does not vary. From the result of the measurement of the polarized radiation luminance component, the temperature of the thin film (2) is calculated. The polarized radiation luminance component is a p-wave polarized radiation luminance component polarized by a polarizer (3), and the p-wave polarized radiation luminance component is measured by means of a radiometer (4). A pseudo-black body (5) is disposed in a position mirror-symmetrical with respect to the radiometer (4). The radiometer (4) is shielded against the background radiation. The temperature of the pseudo-black body (5) is measured, and the measured temperature is taken into consideration in the calculation of the temperature of the thin film (2).
