Photonics Control Technology Team

Our team investigates the new optical technologies for environment measurement from space, energy resource with solar energy, medical diagnostic and treatment system. These fields are of important to maintain the social climate that the human race can live safely. We develop remote-sensing system to measure poisonous gas, lidar as an atmospheric monitor to acquire atmospheric information necessary for the high energy cosmic rays observation and solar-pumped laser for advanced energy source. We also work on the development of the tunable laser for the medical sensing. The particle control and precise measurement with high power Lyman α coherent source is another research field of our unit.
