针对爆炸过程反应剧烈,温度高、速度快,难于直接测得温度分布的问题,提出一种利用多光谱辐射测温理论与光学层析技术相结合的三维爆炸温度场的重建方法.通过建立依据参考温度的多光谱测温数学模型,对光学层析算法进行预处理,采用正交辐射传感器阵列进行数据采集,选择级数展开迭代算法进行分析,完成对爆炸温度场的重建研究.
Considering the difficulty in measuring the distribution of explosion temperature field because of the fierce, fast and high-temperature reaction, the three-dimensional explosion temperature field reconstruction method is proposed, which is based on multi-wavelength thermometry and optical computed tomography. Furthermore, in order to complete the study of explosion temperature field reconstruction,mathematical model of multi-wavelength thermometry is founded and optical eomputed tomography algorithm is treated beforehand. Besides, a radiation data collection system by orthogonal radiation sensor array is designed and series iterative algorithm be chosen.
