Abstract可调谐二极管吸收光谱技术(tunable diode laser absorption spectroscopy,TDLAS)已成为超声速燃烧的重要测量手段之一.为提高其空间分辨能力,需发展基于TDLAS,结合层析成像术的二维断层成像术(tunable diode laser absorption tomography,TDLAT).设计了一套基于6平行光束--旋转测量的新型TDLAT系统,吸收波长为7185.6cm-1和7444.3cm-1双线,采用分时--直接吸收探测策略.重建中,使用代数重建算法,先分别反演计算两吸收线的吸收率和吸收比分布,再获得温度和浓度分布.利用该系统,在CH4/Ai...
