| Research Abstract |
In this study, angular-dispersive-type micro-Raman spectroscopy was developed. In this instrument, the angular dispersive optical system that laser light was made incident from three directions (0, 50, and 100 degree) and detection was in the direction of 0 degree, was constructed. It was successful to determine the crystallographic orientation of Alumina by using angular dispersive properties. Especially, the directions of a-axis and c-axis were determined. Finally, for polycrystalline partially stabilized zirconia (PSZ), the possibility of stress measurement by angular dispersive properties was examined. The amount of Raman shift of PSZ under mechanical loading changed with the incidence angle, and the angular dispersion property was confirmed to be useful for stress measurement of polycrystalline material.
