Paper Abstract

Pyrometer calibration is a common task in most radiometry labs. When measurements are made in a wide range of temperatures, it is necessary to use different blackbody radiators to cover the whole interval. A problem that arises with this is the lack of concordance in the signals measured by the pyrometer when taken from different radiators. In a recent publication, Fourier theory is applied to measure the temperature of inhomogeneous objects, particularly periodic objects1. Those results are used to measure the temperature of the coil filament of a reference lamp (in a range from 300 K to 3300 K, approximately), considering the filament as a periodic object, which is modeled with a simple functions arrangement. Measurement verification is also presented by comparing our calculations to the experimental data of the lamp's temperature.
