摘要
利用光学层析技术重建温度场是测量复杂流场领域的难点问题,本文在研究现有重建方法及其适用性的基础上探讨了光学层析重建温度场时投影数据的转化以及由共轭梯度法求解投影方程组实现温度场的重建,用数值模拟考察该方法对单峰对称温度分布的重建效果,重建结果表明这是一种有效的方法,可以用于重建整个温度场分布,相比传统的测温方法有很大的改善。
Using OCT to reconstruct the temperature field is a difficult problem in the field of complex flow field. Based on the study for the existing reconstruction methods and their applicability, the paper studies the temperature field reconstruction with the CG algorithm and it uses numerical simulation method to study the effect of temperature reconstruction. The results show that this is an effective method. It can be used to reconstruct the entire temperature distribution, and has great improvement compared to traditional methods.
