| 摘 要： | 脉冲红外热成像使用脉冲热源，热源中具有广泛的频率分量，而锁相红外热成像技术使用周期热源，热源频率单一。两种热成像技术的热源工作方式和数据处理方式不同，两种技术各有优缺点。本文利用两种技术分别对电路板和平底洞试件进行了检测，通过实验结果来说明两种热成像技术的区别以及各自的优缺点。

| Abstract: | Pulsed infrared thermography uses the pulsed heat source which has a plurality of frequencies,but lock-in infrared thermography uses the periodic heat source which has only a single frequency.Since the work-style of heat source and data processing method are different between these two technologies,the article uses the two above mentioned technologies to inspect the PCB and Back-drilled flat bottom holes sample,according to the result of two technologies,differences between the two technologies and their advantages and disadvantages are presented. |
