Scintillator for Imaging Terahertz Light

This technology presents a novel radiation detection method that transforms Terahertz (THz) radiation into visible or infrared light by employing field-enhancing structures, such as split ring resonators or micro-slits, in conjunction with electroluminescent materials. These field-enhancing structures amplify the electric field of incoming THz radiation, prompting the electroluminescent material to emit visible or infrared light. The emitted light can be detected and measured using a device like an avalanche photodiode, offering a cost-effective solution for THz radiation detection at room temperature. This innovation has the potential to revolutionize security screening by enabling efficient and safe identification of concealed hazardous substances.
