Lab-based radiometric concepts for undergraduate and graduate students

Paper Abstract

Radiometry is formally defined as the science of characterizing or measuring how much electromagnetic energy is present at, or associated with, some location or direction in space. It involves the measurement and quantification of optical flux. It has evolved separately in the fields of physics, illumination or vision, and engineering, and as a result a host of terms are used to describe various radiometric concepts. Over the years there have been various texts on the subject to help demystify some of these concepts with less emphasis on “practical" radiometry (i.e., meaning laboratory examples). At the Rochester Institute of Technology (RIT), an entire course has been devoted to the subject along with a dozen or so hands-on laboratory exercises. This paper will discuss our approach to the dissemination of “practical" radiometry through exercises that talk about construction of radiometers, inverse square law, radiometric and spectral calibration (of a spectrometer), diffraction gratings, blackbodies and sources, spectral transmission and reflectance measurements, detector spectral responsivity measurements, transfer calibration, and more.
