Outline of Final Research Achievements

In this research, we aimed to make a home-made optical-beating-type Brillouin scattering spectrometer, and apply it to fluids and minerals, and to develop a system which applicable to microscopic samples. However, due to the earthquake that occurred in October 2016, the implementation of the research was delayed severely. Furthermore, a laser which was planned to be used in this research also had problems. Currently, the Brillouin scattering spectrometer has been assembled, and optical alignments are being carried out. We plan to continue this research in the near future, so that our original goal can be achieved.
