Outline of Final Research Achievements |
A structured illumination Raman microscopy has been developed in order to realize a label-free analytical imaging technique with an improved spatial resolution. The light illumination optics has been newly designed and implemented to a line illumination Raman microscopy. The introduction of structured pattern into the line illumination for Raman scattering detection provided about a twice improvement of the spatial resolution in practical conditions, which corresponds about 1.5-fold improvement from the theoretical limit. The improvement of the spatial resolution has been confirmed by observing polymer nanoparticles ( a mixture of polystyrene and PMMA), carbon nanomaterials (CVD graphene and graphite), biological tissue (fibrous structure of lipid) samples.
