As 5 G ever becomes a part of everyday life and 6 G is also on the agenda

terahertz technology has gradually become known by the public

and is referred to as the "third eye" for human beings to understand the world.

Terahertz is considered one of the top ten technologies that will change the world due to its unique properties. In 2019

astronomers were able to observe a black hole for the first time

using a terahertz astronomical telescope. Terahertz is no longer far away from our lives

whether it is information

medicine

or food safety and other fields. It is everywhere

triggering major changes in people's work and lifestyle.

Today's guest of Light People is an internationally renowned scholar who has been engaged in terahertz research for many years

Professor Xi-Cheng Zhang works at the University of Rochester

one of the three major optics educational centers in the United States. As a pioneer in the field of terahertz technology

after years of practice

he has successfully generated terahertz waves using water

changing how we see water with THz wave forever.
