Abstract
Most pyrometers for industrial applications use one or two wavelength bands to measure energy in order to determine the target temperature, but this can lead to errors from incorrect or unknown emissivity or non-greyness. Using a tuneable detector based on a Fabry Perot filter, temperature measurement across a greater number of wavelengths can be performed, and potentially eliminate errors arising from atmospheric gasses and surface emissivity.
