Abstract

It has been qualitatively demonstrated that the surface currents induced by incident electromagnetic radiation produce I2R heating detectable through thermographic techniques. This paper presents the progress to date toward obtaining quantitative comparisons of known surface current amplitude distributions with those obtained through infrared thermographic analysis. Data for correcting for the directional dependence of IR emission from various surfaces is given, a method of digital analysis of the thermographic data is discussed, and an actual thermographic determination of the surface currents on a square flat plate is presented. These experimental results represent a necessary step in the effort of infrared detection and measurement of the current amplitude distributions on complex shapes.
