摘要
红外热成像无损检测技术是近年来发展较快的一种新型数字化无损检测技术,因为其具有便捷、高效、直观、探测面积大以及远距离非接触探测等优点广泛应用于航天航空、军事、电池、电力、电子、建筑、医疗、文物保护等诸多领域。本文主要对红外热成像无损检测技术中卤素灯、超声波、激光、脉冲光等几种主要热激励方法的特点及研究现状进行了介绍与对比,同时也介绍了红外热成像无损检测图像序列处理技术中热信号重建理论、锁相法、相位法、主成分分析法、动态热层析法、相似光流法等处理方法的研究现状,最后展望了红外热成像无损检测技术的未来发展趋势。
Infrared thermography is a new type of digital non-destructive testing technology which has developed rapidly in recent years,because it has the advantages like convenient,efficient,intuitive,large detection area and long-distance non-contact detection,which is widely used in aerospace,military,battery,power,electronics,architecture,medical treatment,cultural relics protection and many other fields.This paper mainly introduces and compares the characteristics and research status of several main thermal excitation methods in infrared thermography,such as halogen lamp,ultrasound,laser,pulsed light,etc.At the same time,it also introduces the research status of Thermal signal reconstruction(TSR),Lock-in thermography(LT),Pulse phase infrared thermography(PPT),Principal component analysis(PCA),Dynamic thermal thermography(DTT)and Likeness optical flow(LOF)in infrared image sequence processing technology.Finally,the future development trend of infrared thermography is prospected.
