为了得到温度场的3维温度分布情况，采用数字全息方法，并将拉东变换的图层重建理论应用到数字全息的后期图像处理过程中，进行了理论分析和实验验证，取得了温度场的3维相位和温度数据。结果表明，此方法重构的温度场3维数据和阿贝尔变换重构的温度场数据相一致，证明了该方法的可行性。

In order to obtain the temperature distribution of temperature field, using of the digital holography, adopting the reconstruction theory of drawing layer based on Randon transform into the final image processing in digital holography, after theoretical analysis and experimental validation, 3-D phase and temperature data of the temperature field were obtained. The 3-D temperature reconstructed with this method is conformal with that reconstucted with Abel method so that it is feasible.
