Terahertz electromagnetic waves are considered the waves for the next generation of security checking technology. They can penetrate opaque materials, such as plastics, fibers, papers, and leathers. In addition, they are harmless to humans they cannot penetrate human skins. Moreover, because their frequencies are higher than those of millimeter waves, higher resolution and more detailed information is expected than the millimeter wave-based technologies In this study, we describe the trends and prospectives of terahertz technology as security checking technology that can be directly applied to a human body.

Modern imaging technologies utilizing electromagnetic waves are indispensable in our daily lives. Applications, such as television and smartphone screens, radar imaging for weather forecast, and medical imaging, can be attributed to technology developments in various electromagnetic regions. Terahertz (THz) waves, electromagnetic (EM) waves located between far infrared and microwave regions, had left unexplored EM waves. Recent advances in technology have led to various two-dimensional and three-dimensional THz imaging techniques. In this article, we explain THz imaging techniques as well as the experimental results from our laboratory. Additionally, we introduce commercial THz cameras developed worldwide. Finally, we present the applications of THz imaging techniques.

「연구실안전법」에 따르면 기업부설연구소 또는 연구개발전담부서의 경우 연구실 안전과 관련한 기술적인 사항에 대하여 연구주체의 장을 보좌하고 연구실책임자 등 연구활동종사자에게 조언·지도하는 업무를 수행하는 연구실안전환경관리자를 지정할 필요가 없기 때문에 연구실 안전관리를 수행할 수 있는 전문가가 없는 것이 현실이다. 기업부설연구소 또는 연구개발전 담부서에 있어서 「연구실안전법」에 따른 연구실안전환경관리자의 지정에 관한 내용을 검토하고 그 방안을 제시하였다.

The terahertz wave (THz wave) is a band between infrared and microwaves and is defined as an electromagnetic wave having a frequency of 0.1 to 10 THz band. THz waves have the property of transmitting nonpolar materials, which the visible light cannot be transmitted, such as ceramics, plastics, and paper; and the photon energy is low, such as several meV. For this reason, non-destructive testing equipment based on THz imaging technology can be applied to the industrial field. Recently, THz imaging technology was applied in wide industrial fields, such as automobiles, batteries, food, medical, and security, and being actively studied. In this paper, we describe the research trends of terahertz imaging technology and experimental results. Furthermore, we summarize the recent commercialized terahertz camera. Finally, we present the research results in the field of the human security scanner system.
