摘要
提出了三步相移全息有限角ＣＴ技术重建热气流温度场．实验中采用双参考光相移方法，在正交两个方向上各±８°的有限角范围内，应用联合代数迭代法，重建了三维热气流温度场．结果表明。
The three step phase shifting holographic limited view CT technique is presented. We have reconstructed the three dimensional temperature field of thermal air flow, using SART by two reference beams three step phase shifting method in our experiment, from limited view angle of 8 degrees in each orthographic dual directions. Satisfied results are obtained in this technique.
