Abstract
A temperature monitoring technique for collecting radiation intensity (blackbody emission) across a broad wavelength range. A solid state spectrometer () acquires spectra from a sample () in real time and resolves the spectra to a radiation intensity (I) versus wavelength (λ) curve. This curve is fitted to Planck's equation using a non-linear least squares fitting analysis. The system can be configured to self-calibrate and then lock in an amplitude value (A) which is used in subsequent temperature measurements by fitting to the blackbody emission curve. Preferably, the spectrometer () is flat field corrected () in an initial step to counteract variations in the spectrometer response with wavelength.
