Radiometry Sensing the World
This article describes some of
the methods developed to make accurate measurement of light a reality. We describe three ongoing research programs aimed at establishing measurement chains between fundamental optical flux measurements and the more practical quantities of commercial and scientific interest: spectral irradiance, spectral radiance, and radiance temperature.
