Important progress occurred in pulse-stimulated thermography, in particular thanks to the TSR technique, a technique based on the decomposition of thermograms on a logarithmic polynomial basis and the use of the logarithmic derivatives to enhance the detection of defects in structures. Its fields of application begin to broaden to the characterization of transient internal heat sources in experimental mechanics and biomedicine. The TSR technique is presented, in particular the last developments leading to the production of a unique synthetic image. Two recent examples of applications in experimental mechanics and biomedicine, taken from literature, are described: in situ detection of damages in a composite material during mechanical tests and in vivo visualization of subcutaneous functional angioarchitecture in humans.

脉冲激励热成像技术取得了重要进展，特别是由于TSR技术，基于对数多项式分解热谱图的技术以及使用对数导数来增强对结构缺陷的检测所致。它的应用领域开始扩展到实验力学和生物医学中瞬态内部热源的表征。介绍了TSR技术，特别是导致产生独特合成图像的最新进展。描述了两个最近在实验力学和生物医学中应用的例子：在机械测试过程中原位检测复合材料中的损伤，并在体内可视化人类的皮下功能血管结构。
