We developed the hardware and software of scanning photoacoustic microscope(SPAM) composed of low price parts. We found that our SPAM could be used well to understand fundamental characteristics of a surface flaw on machinable ceramic, surface and subsurface flaws in epoxy and the distribution of carbon fiber in the CFRP as an equipment of nondestructive testing.Amplitude and phase of a photoacoustic signal generated from an epoxy resin on various backings(aluminum, white acrylic resin and black-coated white acrylic resin) were measured by this SPAM.The experimental results were as follows.The photoacoustic signals for light-reflective backings were generated from the epoxy resin on the backing, while photoacoustic signals for light-absorptive backing were generated from the backing itself. We proposed a "model for PA imaging of" a drilled hole in the epoxy resin sample.

我们研制了由低价格元器件组成的扫描光声显微镜（SPAM）的硬件和软件。我们发现，SPAM可以很好地用于了解可加工陶瓷表面缺陷、环氧树脂表面和亚表面缺陷以及CFRP中碳纤维分布的基本特征，可以作为一种无损检测设备。实验结果表明：光反射背衬的光声信号是由背衬上的环氧树脂产生的，而光吸收背衬的光声信号是从背衬本身产生的。我们提出了一个“模型PA成像”钻孔的环氧树脂样品。
