综述了三种用于金属构件裂纹定位和成像的热成像无损检测技术。这些技术是：热超声学（声波IR、超声激励热成像）;激光点热成像;和脉冲涡流激励热成像。这三种技术进行了解释，并给出了他们的表现在成像以及特征的裂缝的例子。有关的技术的实际和可靠的实施的因素进行了讨论。
Work on three thermographic NDE techniques that have been developed to locate and image cracks in metallic components is reviewed. These techniques are: thermosonics (sonic IR, ultrasonically stimulated thermography); laser spot thermographic imaging; and pulsed eddy current stimulated thermography. The three techniques are explained and examples are given of their performance in imaging well-characterised cracks. Factors concerning the practical and reliable implementation of the techniques are discussed.
