Abstract
An apparatus and method for non-contact real-time measurements of temperature and emissivity profiles of radiant targets with unknown spectral emissivity. The selected points or regions on the radiant target are imaged onto an array of photodetectors through an assembly of narrow-band optical filters. Produced multi-wavelength images of the radiant target are processed by the computer workstation and 1D or 2D temperature and emissivity profiles are obtained by means of the curve-fitting of radiometric model of imager sensor response to measured response and performing spatial interpolation of the results. Method for calibration of said apparatus by means of curve-fitting of radiometric model of the apparatus to sensor responses obtained by imaging pre-calibrated blackbody. Method for compensation for inherent non-linearities of pyrometer response.
