Space Metrology Group conducts research on optical systems for space satellite cameras, ultra-precision reflective mirrors for infrared, and extreme measurements and super-materials under multi-extreme conditions in space, such as high temperature, high pressure, microgravity, and ultra fast transition, metastable state.
We aim to establish optical systems for space/advanced strategic fields and to develop new measurements and super-materials applicable to future extreme industries, including space exploration, national defense, and future energy sources.
