| Outline of Final Research Achievements |
In this study, three types of Raman spectroscopes are developed. The first is the two dimensional direct imaging Raman instrument, the second is the multi-point focus multi-point micro-Raman spectroscope and the last is the single-focus multi-point micro-Raman spectroscope. By using these instruments and conventional micro-Raman spectroscopes, fast two dimensional imaging and multiscale evaluation of phases and stresses/strains in materials become possible. By conventional micro-Raman spectroscope, the changes of two E2g degenerately separated Raman peak shifts in Graphene are measured and the possibility of stress components measurement of carbon fibers in resin-based carbon fiber reinforced plastics (FRP) is indicated. However, further considerations are necessary for matrix stress measurement in FRP.
