Abstract:
The theories of classical radiance temperature (RT) and effective wavelength for pyrometry neglect the influence of ambient radiation,, and the actual measurement theories deviate from the strict definition of RT. Considering the effect of the ambient radiation, the new concept of the effective radiance temperature (ERT) which is suitable for a measurement at an arbitrary temperature is proposed. Based on the band-pass radiation thermometer, the theories of integral effective radiance temperature and equivalent wavelength are developed further, in which the deviations from the definition of ERT are avoided.展开更多
