Abstract:
Advancements in the performance and ease of use of absolute photodetectors
based upon electrical substitution principals offers the possibility of a
simplified and more accurate way to transfer the fundamental radiometric,
photometric, and pyrometric units from NIST to the U.S. technical
establishment. The history of electrical substitution radiometers at NIST
is briefly reviewed and the implementation of the latest generation absolute
cryogenic radiometer is discussed. Procedures to maintain fundamental units
based upon a detector approach are reviewed in a general way with references
to the technical literature for detailed discussion. It is proposed that
NIST customers consider adopting the suggestions made in this technical note
to simplify and improve their optical radiation based calibrations.
