An imaging system was developed that emits and detects electromagnetic radiation at terahertz frequencies — higher than radio waves but lower than the long-wave infrared light used for thermal imaging. Imaging using terahertz radiation has long been a goal for engineers but the difficulty of creating practical systems that work in this frequency range has resulted in the “terahertz gap.”
