This paper attempts to determine the blackbody radiation temperature measurement theoretical and practical limits of resolution, the calculation is limited to non-color filter Si, Ge, Insb photodiodes and the temperature is limited to the range of 100 ℃ ~ 1 50 ℃, (BB) structure to determine the measurement geometry, the field of view angle of 3 °, the observation area of 1mm2, assuming the long-term noise performance of the detector is the best technical level, the calculation shows that the temperature at 100 ℃ ~ 280 ℃ Within the range, Insb all passband pyrometer the best resolution is 15mK ~ 4 0mK; temperature in the range of 2 80 ℃ ~ 50 0 ℃, Ge all passband pyrometer the best resolution is 6mK ~ 1 5mK, and the temperature is in the range of 50 0 ℃ ~ 1 1 0 0 ℃. The best resolution of Si full pass optical pyrometer is 2mK ~ 8mK. These results require that the temperature stability of the detector is very good 0 0 1K).
