Abstract

Based on the Black-body radiation theory, a multi-wavelength photoelectric detection system for the on-line measurement of temperature and components of the detonation field is designed. In this system, the detonation spectrum is split by bifurcated optical fiber and filters, then, received by the photoelectric-detectors and convert to electrical signal. Finally, the temperature evolution process is derived through regression algorithm. Besides, concentrations of certain components can also be revealed through real-time detection of corresponding spectral lines. The spectral response coefficients and the whole system are calibrated with a standard tungsten lamp and a standard radiation source respectively. With this system, experiments are carried out, and, the variations of denotation temperature and concentrations of some key components are recorded.
