Experimental Multi-wavelength Imaging Pyrometer (M-WIP) is presented for remote sensing of temperature profiles of targets with unknown spectrally varying 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 X 122-element PtSi IR-CCD imager and an assembly of narrow-band striped IR filters in the spectral range from 1797 nm through 4512 nm. The M-WIP system was calibrated against a commercial blackbody source over temperature range from 450 degree(s)C to 950 degree(s)C. The signal processing included background subtraction, compensation for variation of dark current with detected signal and correction for non-linearities of IR imager response. Initial M-WIP measurements demonstrated real-time temperature resolution (Delta) T of +/- 1 degree(s)C for blackbody target over temperature range from 600 degree(s)C to 900 degree(s)C. Temperature resolution of +/- 4 degree(s)C was demonstrated for the blackbody source viewed through the double polished silicon wafer with unknown spectral transmissivity in the temperature range from 500 degree(s)C to 950 degree(s)C.
