A breakthrough in imaging technology has been achieved by a research team at the University of Texas Dallas campus with the development of miniature terahertz chips that can be integrated into smartphones. These chips utilize millimeter waves that are safe for the human body to enable imaging through tissues.
Industries such as factory product inspections and airport baggage screenings have a significant demand for imaging technology in the fields of industry and safety assurance. While conventional imaging devices typically use X-rays, concerns have been raised about the potential impact on operators handling X-ray equipment daily, leading to precautionary measures such as the installation of shielding rooms at inspection sites.
The research team turned their attention to terahertz imaging technology utilizing 200-400GHz waves as a safe alternative to X-rays. After extensive trial and error, they successfully developed miniature terahertz chips for imaging using this technology, as reported in March 2024.
These terahertz chips, measuring 0.5×0.5mm, can be embedded in small devices like smartphones. Designed to only function at close range for privacy protection, the imaging must be performed with the observation target within 2.54cm proximity.
The team highlights the potential applications of these chips in product inspections and foresees designing chips that can be used at distances up to 12.7cm in the future, paving the way for further advancements in imaging technology.
