Approximation of melting plateau of large-area HTFPcells used for spectral irradiance realization
2021
This paper adopted an approximation of a melting plateau to solve
the problem that temperature data cannot be monitored continuously when
measuring the spectral irradiance of a large area tungsten carbide–carbon
high-temperature fixed-point blackbody at each measured wavelength. Tests
with fully measured curves showed that the method has a rather small
deviation from the measured data of 0.017 K maximum, which corresponds to
the spectral irradiance deviation of 0.005% at 500 nm. The maximum
relative deviation between the Akima fitting method and the measured
temperature in terms of spectral irradiance was 0.002%, which was better
than −0.067% of a single temperature of 3020.11 K method and 0.026%
of a linear interpolation method.
