随着社会的发展,科技的日益发达,红外热成像无损检测技术应运而生,它比传统的无损检测技术更能适应现代各种新兴企业和传统工业的发展。本文对红外热成像无损检测技术现状发展做了简要介绍,包括脉冲红外检测、光脉冲热成像技术、压力容器无损检测等原理,介绍了国内外相应的现状及发展,并给出了部分的应用案例,最后总结了该技术的发展趋势。 With the development of society and the increasing development of science and technology, infrared thermography nondestructive testing technology came into being. It is more adaptable to the development of all kinds of emerging enterprises and traditional industries than the traditional nondestructive testing technology. In this paper, the status quo of non-destructive testing of infrared thermal imaging technology is briefly introduced, including the principles of pulse infrared detection, optical pulse thermal imaging and pressure vessel non-destructive testing. The corresponding status quo and development at home and abroad are introduced and some applications are given Case, finally summarizes the development trend of the technology.
