Terahertz imaging system for remote sensing and security applications

The most recent developments in THz technology and new explorations show that THz waves are ideally suitable for the remote sensing and security applications. And unlike X-ray, THz waves do not penetrate living cell material and are completely safe for humans. In this paper, we describe the implementation of a 0.435 THz imaging system with 1 mm-scale resolution, which can successfully detect concealed objects. Our results indicate a promising future of THz technology development.
