针对具有轴对称特性的火焰，将计算机层析成像技术与激光吸收光谱技术相结合，提出了基于单角度投影方法，并应用于轴对称温度分布的二维图像重建。通过数值仿真，利用代数重建算法通过迭代对具有环形温度分布的火焰温度场进行重建，以初步验证该方法的可行性。本研究结果可以用于燃烧诊断中二维轴对称温度检测。

In this paper,computer tomography is combined with laser absorption spectroscopy to recon-struct axisymmetric temperature distributions. By using the algebraic reconstruction technique(ART),a single view projection manner was proposed to reconstruct the two-dimensional temperature distributions. To validate the feasibility of the proposed methods,numerical simulation verification was carried out by using annular distributed temperature profile. The results show that the proposed methods can be used to monitor the two-dimensional axisymmetrical temperature distribution in combustion diagnosis.
