An Independent Retrieval Algorithm of Multiwavelength Pyrometer
An independent retrieval computing algorithm for true temperature detection of multi-wavelength pyrometer (MWP) is explored based on gradient projection iteration (GPI) method.Its advantage is no assumption equation of emissivity in advance to realize the spectral emissivity recognition for all spectral channels.6 kinds of typical emissivity distribution materials is simulated by proposed GPI,the retrieval result shows that the true temperature relative error is lower than 1.5% even if the 5% random noise is input,abs error is lower 30K.Meanwhile the spectral emissivity also is obtained the similar identical distribution.
