A novel thin-filament pyrometer is presented. It involves a consumer-grade color digital still camera with 6 megapixels and 12 bits per color plane. SiC fibers were used and scanning-electron microscopy found them to be uniform with diameters of 13.9\text{\hspace{0.17em} μm} . Measurements were performed in a methane–air coflowing laminar jet diffusion flame with a luminosity length of \text{72 \hspace{0.17em} mm} . Calibration of the pyrometer was accomplished with B-type thermocouples. The pyrometry measurements yielded gas temperatures in the range of 1400–2200 K with an estimated uncertainty of \pm \text{60 \hspace{0.17em} K} , a relative temperature resolution of \pm \text{0.215 \hspace{0.17em} K} , a spatial resolution of \text{42 \hspace{0.17em} μm} , and a temporal resolution of \text{0.66 \hspace{0.17em} ms} . Fiber aging for 10 min had no effect on the results. Soot deposition was less problematic for the pyrometer than for the thermocouple.
