The intensity of the infrared radiation emitted by objects is mainly a function of their temperature. In infrared thermography, this feature is used for multiple purposes: as a health indicator in medical applications, as a sign of malfunction in mechanical and electrical maintenance or as an indicator of heat loss in buildings. This paper presents a review of infrared thermography especially focused on two applications: temperature measurement and non-destructive testing, two of the main fields where infrared thermography-based sensors are used. A general introduction to infrared thermography and the common procedures for temperature measurement and non-destructive testing are presented. Furthermore, developments in these fields and recent advances are reviewed.
物体发出的红外辐射强度主要取决于其温度。在红外热成像技术中,这一特性有多种用途:在医疗应用中作为健康指标,在机电维护中作为故障迹象,或在建筑物中作为热损失指标。本文对红外热成像技术进行了综述,特别关注两个应用领域:温度测量和无损检测,这是基于红外热成像技术的传感器的两个主要应用领域。文中介绍了红外热成像技术的一般情况以及温度测量和无损检测的常用程序。此外,还综述了这些领域的发展情况和最新进展。
