| Research Abstract |
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.
