Abstract

Circular dichroism (CD) has been used to analyze chirality in molecules. These years, it has been reported that spatially extended chiral systems, such as crystals, molecular assemblies and nanostructures, also show CD activity. In order to explore properties of the CD activity and its physical origin, we developed a CD microscope and visualized spatial CD distribution observed in the chiral systems of metallic nanostructures, biological cells, and so forth.
