Soft matter, such as liquid crystals, phospholipid membranes, surfactants, emulsions, gels, polymers, and colloids, are formed by the hierarchical self-assembly of molecules, and the structures can span over from the micro to macro length scales. For example, biological tissue is one of the hierarchical structures of soft matter that is more sophisticated and complex than others. On the other hand, higher symmetry can be recovered in the gel or glass state in low temperature rather than original liquid crystalline state in higher temperature regions. We have designed and constructed new types of the microscope to get directly the spatio-temporal image of the "dynamic heterogeneity" in the soft matters.

软物质，如液晶、磷脂膜、表面活性剂、乳液、凝胶、聚合物和胶体，是由分子的分层自组装形成的，其结构可以跨越微观到宏观的长度尺度。例如，生物组织是软物质的层次结构之一，比其他组织更复杂。另一方面，在低温的凝胶或玻璃状态下可以恢复更高的对称性，而不是在高温区域的原始液晶状态。我们设计并构建了新型显微镜，以直接获得软物质“动态异质性”的时空图像。
