Outline

Terahertz (THz) wave has the unique characteristics such as the transparency to many soft materials and their spectral absorption features. These characteristics can be utilized for many applications in various scientific and industrial fields. In this team, we are developing novel technologies, science and applications in THz sensing, imaging and detection. In particular, we are conducting research and development on the control of molecular structure and function by THz-wave irradiation, high-sensitivity imaging and observations using superconducting detectors as well as the collaborative research and development with companies.
