Abstract

Multi-wavelength imaging pyrometer (M-WIP) is presented for remote sensing of temperature profiles of targets with unknown emissivity. A software package was developed for calibration and real-time M-WIP measurements. An experimental 7-filter line-sensing M-WIP system was implemented with a 320×122-element PtSi IR-CCD imager. The M-WIP system was calibrated against a commercial blackbody source over temperature range from 450°C to 900°C. The signal processing included background subtraction and compensation for variation of dark current with detected signal and nonlinearity of IR imager response. Initial M-WIP measurements demonstrated real-time temperature resolution ΔT of ±1°C for blackbody target over temperature range from 600°C to 900°C.
