ADVANCES AND CHALLENGES IN RADIATION THERMOMETRY
要約
The central problem in radiation thermometry is
inferring target temperature from spectral radiance
observations under conditions when its emissivity is
unknown or variable and in the presence of irradiation
from its surroundings. Dual-wavelength and
multispectral emissivity compensation methods are
reviewed and their application to aluminum alloy and
steel galvannealing processes are evaluated.
Approaches utilizing auxiliary devices in addition to a
radiometer which aim to reduce emissivity effects are
overviewed. The need for improved temperature
measurement technology in primary metals,
petrochemical furnaces, and semiconductor processing
are discussed.
