Characterization of radiometric transfer standards based on silicon trap detectors
We present the characterization of the properties of the silicon trap detectors used in the construction of the traceability chain for radiometry at the Brazilian Institute of Metrology - Inmetro. These devices are used as standards for radiometry and photometry in the transfer of the optical power scale of the primary cryogenic radiometer standard. The experimental results for the spatial non-uniformity, polarization dependence and spectral responsivity are shown and discussed.
