Abstract:

Diffraction losses should be accounted for in calculating the radiometric output for all cavity-type blackbody sources in use. The theoretically predicted source diffraction losses were examined and compared to experimental data obtained during the calibration of a typical AEDC source. The results revealed that the experimental data do not support the use of currently available diffraction correction theories. At this time, the use of diffraction corrections is not recommended for AEDC blackbody sources.
