干涉法是最灵敏和最成功的等离子体诊断方法之一。然而，由于大多数普通干涉系统的设计，操作波长以及因此可以探测的密度和温度的范围受到严重限制。Talbot-Lau干涉测量法提供了通过塔尔博特效应将干涉测量扩展到X射线波长的可能性。虽然已经有几个概念验证实验显示了这种方法的有效性，但直到最近才开始使用Talbot-Lau干涉法探测高能量密度（HED）等离子体的实验。为了改善这些实验设计，我们在这里提出的Talbot干涉仪分析仪（TIA）工具，一个前向模型，用于生成和后处理合成X射线干涉图像从Talbot-Lau干涉仪。虽然TIA可以与任何二维流体动力学代码一起工作，以尽可能接近现实地研究等离子体条件，但该软件已被设计为默认使用流体动力学代码FLASH的输出文件，使该工具用户友好，并可供一般等离子体物理社区使用。该模型已内置到一个独立的应用程序中，可以由任何访问MATLAB运行时安装程序的人安装，并可根据作者的要求提供。
Interferometry is one of the most sensitive and successful diagnostic methods for plasmas. However, owing to the design of most common interferometric systems, the wavelengths of operation and, therefore, the range of densities and temperatures that can be probed are severely limited. Talbot–Lau interferometry offers the possibility of extending interferometry measurements to x-ray wavelengths by means of the Talbot effect. While there have been several proof-of-concept experiments showing the efficacy of this method, it is only recently that experiments to probe High Energy Density (HED) plasmas using Talbot–Lau interferometry are starting to take place. To improve these experimental designs, we present here the Talbot-Interferometry Analyzer (TIA) tool, a forward model for generating and postprocessing synthetic x-ray interferometry images from a Talbot–Lau interferometer. Although TIA can work with any two-dimensional hydrodynamic code to study plasma conditions as close to reality as possible, this software has been designed to work by default with output files from the hydrodynamic code FLASH, making the tool user-friendly and accessible to the general plasma physics community. The model has been built into a standalone app, which can be installed by anyone with access to the MATLAB runtime installer and is available upon request to the authors.
