扫描激光光声显微镜是一种新型的无损检测工具,它的独到之处在于可给出样品次表面和热结构的信息。它是基于光声效应而发展起来的。光声成象是一种具有不寻常特征的新技术,它不仅能对样品进行光学成象,而且也可以对样品的热结构进行成象,在无损检测隐藏在金属、陶瓷等表面以下的裂缝、缺陷等方面具有独到的优点,也可以观察亚表面层中的多孔结构差别;对50～100 μm大小的固体样品的 Scanning laser photoacoustic microscopy is a new nondestructive testing tool unique in that it gives information about the subsurface and thermal structure of a sample. It is based on the photoacoustic effect and developed. Photoacoustic imaging is a new and unusual technique that not only optically images a sample, but also images the thermal structure of the sample and detects non-destructive cracks hidden below the surface of the metal, ceramic, etc. , Defects and other aspects of the unique advantages, you can also observe the sub-surface layer of porous structure difference; for 50 ~ 100 μm size of the solid sample
