Researchers have developed a groundbreaking imaging technology inspired by Superman’s X-ray vision capabilities. Utilizing a tiny imaging chip emitting terahertz (THz) radiation, the team from the University of Texas at Dallas and Seoul National University has made it possible to see through solid objects without the need for external lenses.
The technology, unveiled in 2022, culminates over 15 years of work by Professor Kenneth O and his team. By harnessing 430 GHz rays emitted by the microchip, the researchers demonstrated the ability to penetrate fog, dust, and other obstacles that visible light cannot traverse. The imaging chip, based on complementary metal-oxide-semiconductor (CMOS) technology commonly used in modern processors and memory chips, eliminates the need for traditional lenses, achieving portability in a handheld device.
The newly developed CMOS chip array, comprised of 1 x 3 pixels operating at 296 GHz, represents a significant advancement in imaging technology. This technology has been proven effective in visualizing various objects like USB dongles, blades, integrated circuits, and plastic gears, even when covered by cardboard from a distance of about a centimeter.
In forthcoming tests, researchers plan to improve image quality and explore scanning from a distance of approximately 13 cm, enhancing security and privacy safeguards. The evolution of this technology, with pixels’ performance enhanced by 100 million times over 15 years of research, combined with digital signal processing techniques, marks a significant milestone in imaging innovation.
