High-speed multi-spectral explosion temperature measurement using golden-section accelerated Pearson correlation algorithm
Year: 2025
Type: article
Abstract: To measure transient and extremely high temperatures of explosion processes, a high-speed multi-spectral temperature measurement system was developed. By measuring spectral radiant exitance corresponding to six wavelengths by six fast photodetectors, transient explosion temperature can be extracted in realtime through a linear correlation algorithm accelerated by the golden-section method. Real explosion experiments with the energetic material polymer-bonded explosive demonstrated that the method could rapidly and accurately determine explosion temperatures. Peak explosion temperature up to 3,560 K has been successfully extracted. The proposed method may find applications in explosive evaluations.
