A digital camera with optical filters and a zoom lens recorded the emission intensity of 14 µm diameter Type S silicon-carbide filaments positioned horizontally at different heights above the fire. The system observed filament emission only above 1150 K. Thousands of 30 Hz video frames were collected, and a 50 µm thermocouple provided 3400 independent temperature measurements at locations in the high-temperature zone. A correlation was developed between radiation-corrected thermocouple PDFs and camera grayscale pixel intensity.
