Abstract
Light is the supreme messenger. Light tells us something about the cosmos, the make-up of our bodies, and nearly everything in between. Light carries structural information, chemical information, and information on position and speed, as well as temperature. The information is coded by pattern, color, and intensity. This article will describe some of the latest methods that have been developed to make accurate measurements of light a reality. We describe three current research programs to establish measurement chains between the fundamentals optical flux measurements to the more practical quantities of commercial and scientific interest-spectral irradiance, spectral radiance, and radiance temperature.Citation
