热波成像技术是人们根据热波形成的机理 ,并与现代扫描电镜实验技术相结合而进行的一种显微成像技术。该技术对物质表面和亚表面缺陷进行非破坏性无损检测具有独特的优越性。一、热波成像技术的物理过程热波成像技术按其检测信号方式的不同 ,可分为两类 :第一类为气体传声器光
Thermal wave imaging is a kind of micro-imaging technology based on the mechanism of heat wave formation and combined with modern scanning electron microscopy experiment technology. The technology has unique advantages in non-destructive non-destructive testing of material and subsurface defects. First, the physical process of thermal wave imaging technology Thermal wave imaging technology according to the different ways of detecting signals can be divided into two categories: The first category for the gas microphone light
