Can you imagine that one single small capsule can achieve navigation and positioning

and do gastroscopy of the digestive system? Can you imagine that a machine can automatically complete the task of analyzing more than 4800 new coronavirus samples within 24 h? Don't be surprised

this has become a reality

thanks to Academician Songlin Zhuang and his team

who applied terahertz technology to various fields such as medicine

food safety

ecological environment monitoring

and social security. Dedicating his entire life to optics and terahertz

Academician Zhuang personifies courage

determination and persistence. He believes in science and hard work. He also takes it as his responsibility to pass on the optical spirit and cultivate optical young scientists.

Today

Light Special Correspondents will take you to the University of Shanghai for Science and Technology to see the beginning and experience of Academician Songlin Zhuang's optical road. I believe it will open a window to a different optical world

and allow our readers to appreciate its unique beauty.
