Abstract

Spectroscopic radiometry is divided into two groups: the spectral and quantitative measurement (analysis) of light sources, which can be further divided into two principles: the measurement of rays in all directions and under all angles, and the measurement of rays traveling into a defined direction and under defined angles, and the illumination of a sample by light of a known wavelength, known bandwidth, and known intensity (also called light flux), and the detection of the sample’s response. In principle, the radiometric methods are very closely connected to the illumination techniques described in Section 6.2 of Fundamentals.1 The definitions directly applied in radiometric applications are summarized in Section 5.1 of this book. Other books offer an online introduction and a substantial educational reference on radiometry.
