Outline of Final Research Achievements	A new Raman imaging system using a pair of tunable band pass filters was designed and developed. The pair of tunable band pass filters acts as a flexible filter system for Raman scattering light. Raman images of a certain wavenumber and a certain width could be acquired by the developed system. Basic performance of the system has been tested and Raman images of substance particles on a metal surface was measured, and it was shown that discreet images of the chemical species can be easily acquired. Raman hyper images with high spatial resolution and high spectral resolution can be acquired in a short time.
