锁相热成像技术是材料无损检测中一种有价值的工具，因为它提供了可靠且易于解释的相位图像。本文提出了一种利用散点图对不同锁定频率下的联合收割机相位图进行合成的方法。不仅可以从原始数据中提取缺陷等特征，还可以提取反射系数等热波参数。提取的特征可以追溯到原始图像。此外，偏离预期和众所周知的一维热流模型揭示了测量样品内的横向热流。
Lockin-thermography is a valuable tool in non-destructive testing of materials because it provides reliable and easy-to-interpret phase images. This paper presents a way to combine phase images obtained at different lockin-frequencies by using scatter plots. Not only features like defects can be extracted out of the raw data, but also thermal wave parameters like reflection coefficients. The extracted features can be traced back to the original image. Additionally, deviations from the expected and well-known model of one-dimensional heat flow reveal lateral heat flow within the measured sample.
