无损检测（NDT）是一种用于检测和表征材料从制造到评估材料健康状况而不会对部件造成进一步损害的缺陷的技术。在过去的二十年中，随着尖端技术的发展，主动热成像无损检测作为一个领域已经大大发展。更低成本、更便携、性能更高的硬件的出现，推动了分析技术研究的发展，扩大了热成像技术的适用性，以利用其作为低成本、非接触检测技术的优势。虽然被动热成像是一个高度标准化的过程，但主动热成像在工业标准中相当缺乏。这些标准的制定为主动热成像领域的研究提供了一个机会，使其成为这一过程的一部分。最近关于无损检测研究的行业压力已经发展出一种可量化的无损检测技术的需求，并与材料特性直接相关，从而可以估计剩余使用寿命（RUL），以最大化产品价值。近年来，该领域的研究取得了重大进展。通过热成像数据信号处理的发展，检查将使样品的可重复、可量化的基准测试成为可能，这将使精心控制的质量检查实现自动化；以及测量材料的热性能，这将允许估计组件的RUL。解决这些挑战将增加热成像技术在工业中的应用，增强全寿命工程的工具集，并显著提高拥抱这些发展的行业的竞争力。
Non-destructive testing (NDT) are techniques used to detect and characterise flaws that occur in materials from manufacture through to evaluating the health of the material without causing further damage to the component. With the development of cutting-edge technology over the last two decades, active thermographic NDT has grown considerably as a field. Access to lower cost, more portable hardware with higher performance has fuelled a major drive in research to develop analytical techniques and widen the applicability of thermography in order to exploit its advantages as a low-cost and non-contact inspection technique. While passive thermography is a heavily standardised process, active thermography is considerably lacking in industrial standards. Development of these standards represents an opportunity for research in the field of active thermography to be a part of that process. Recent industry pressure regarding research in NDT has developed a demand for NDT techniques to be quantifiable, and linked directly to material properties, thus allowing an estimation of remaining useful life (RUL) in order to maximise product value. There have been significant research developments in the field over recent years. Through developments in signal processing of thermography data, inspections would enable repeatable, quantifiable benchmarking of samples, which would allow automation of carefully controlled quality checks; and the measurement of thermal properties of the material, which would allow estimation of components’ RUL. Addressing these challenges would increase the deployment of thermography in industry, enhance the toolset of through-life engineering, and significantly improve the competitiveness of industries which embrace these developments.
