GLOSSARY
photometry
The science of the measurement of light intensity, where "light'' refers to the total integrated range of radiation to which the eye is sensitive. It is distinguished from radiometry in which each separate wavelength in the electromagnetic spectrum is detected and measured, including the ultraviolet and infrared.
radiometry
The science of radiation measurement. The detection and measurement of radiant energy, either as separate wavelengths or integrated over a broad wavelength band, and the interaction of radiation with matter in such ways as absorption, reflectance and emission.
