High-speed multi-spectral explosion temperature measurement using golden-section accelerated Pearson correlation algorithm

Blog Article

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 HDMI Type A to DVI-I 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 School Uniforms K has been successfully extracted.

The proposed method may find applications in explosive evaluations.
