Infrared thermal wave detection, scanning and recording of temperature responses in the form of digital signals is considered a powerful supplement to traditional nondestructive testing (NDT) methods. It offers a range of advantages, such as a large testing area, a wide range of applications, a fast testing speed, the fact that there is no need to make contact with the tested objects, and the possibility of presenting test results in a pictorial form [1], [2]. In relation to the interests of this paper, it has been applied to detect ice in the field of aeronautics [3], in marine structures [4] and in wind turbine blades [5].

蜂窝夹层皮内部冰缺陷的红外热检测


红外热波检测、扫描和以数字信号形式记录温度响应被认为是对传统无损检测（NDT）方法的有力补充。具有测试面积大、适用范围广、测试速度快、无需与被测物体接触、可以图形方式呈现测试结果等优点。形式[1]、[2]。就本文的兴趣而言，它已应用于航空[3]、海洋结构[4]和风力涡轮机叶片[5]领域的冰检测。
