Principles of Optical Radiometry and Measurement Uncertainty



Bettye C. Johnson, Howard W. Yoon, Joseph P. Rice, Albert C. Parr


The fundamental concepts of optical radiometry are developed from basic principles, with detailed explanations for radiance, irradiance, and reflectance. Examples of radiometric standards, in particular radiometers and reference sources are given, and the methods of realization of spectral radiance, spectral irradiance, or spectral reflectance are described. The concept of the measurement equation is introduced and applied to methods of estimating uncertainty for measurement results. Examples of this approach are given, using lamp standards of spectral irradiance as a demonstration. The terminology and recommended protocols presented here are based on international bodies such as the International Organization for Standardization (ISO), the International Commission on Illumination (CIE), and the Bureau International des Poids et Mesures (BIPM).
