A spectroradiometric pyrometer was developed to measure temperatures of shock-heated gases with time resolution of about 10 μsec. Gas temperatures in shock-heated CO2–N2 mixtures and in self-sustaining detonations were determined by simultaneously measuring infrared spectral radiance and absorptance at selected wavelengths in CO2 and H2O band spectra. By Kirchhoff’s law, the ratio (radiance/absorptance) equals the Planck blackbody radiance, from which the temperature is easily found. The measured temperatures agreed with values calculated from the measured shock velocities.
