Temperature measurement of blackbody using filter radiometer

The tracing ways and methods for temperature measurement of blackbody were introduced. The influences of the absolute spectral response of detector, the lens transmittance and the area effect on the blackbody temperature measurement were analyzed.The test results show that the blackbody temperature can be transmitted and traced by the standard detector. Compared with traditional tracing methods, the accuracy of blackbody temperature measurement transmitted by the standard detector can increased by an order of magnitude, reaching a level of 0.8%.
