Phase Measuring Deflectometry based technique for Detecting Defects in Materials via Heat Flow Visualization

This data contains a Word document that includes a flow chart for the algorithm used for phase extraction using Fourier Transform and a discussion of simulation results that demonstrate how thermal signatures vary due to different material inhomogeneity. It also contains three video files V1, V2, and V3 capturing the spatiotemporal evaluation of thermal signatures for three different thermal anomalies.本数据集包含一份Word文档，其中收录了采用傅里叶变换（Fourier Transform）实现相位提取的算法流程图，同时附有针对仿真结果的讨论，阐明了材料不均匀性如何导致热特征发生变化。此外，数据集还包含V1、V2、V3三个视频文件，分别记录了三种不同热异常的热特征时空演变过程。
