| 摘 要： | 本文我们将联合代数重建技术应用于光学层析重建透明物体的折射率分布．建立了一简易的能获得多方位干涉条纹数据的全息干涉系统．利用双曝光全息干涉技术，对长方形开口上方的热气流场进行了实际测量，重建出了气流场中一个截面内的温度分布．重建温度值与热电偶实测值一致。

| Abstract: | In this paper,simultaneous algebraic reconstruction technique has been applied to optical tomography to reconstruct refractive index distribution of a transparant medium.A simple holographic interferometric system from which the multidirectional interferometric data can be obtained has been established.A heat air flow field above rectgular hole has been investigated by holographic interferometry with doubleexposures,and temperature distribution of a section in the air flow field has been reconstructed. The values of reconstructed temperature are consistant with the values measured by thermocouple. |
