Development of 3DXRF instrument and application to forensic science

我们成功地研制了一台带真空室的台式3D-XRF仪器。我们还开发了一套用于评估空间分辨率的标准薄层。在世界顶尖水平的L线上，它大约是11微米。该仪器的优点之一是对固体样品内部的非破坏性元素成像。我们将该技术应用于一些法医领域的层状材料，如汽车漆片。证明了对法医样品进行深度剖析和深度成像是可能的。

We successfully developed a desk-top 3D-XRF instrument with a vacuum chamber. We also developed a set of standard thin layers for evaluating the spatial resolution. It was about 11 micro meters at Au L line, which is a top level in the world. One of the advantages of this instrument is a non-destructive elemental imaging of inside of the solid sample. We applied this technique for some layered materials of forensic field, such as car paint chip. It was demonstrated that depth profiling and depth imaging were possible for forensic samples.
