Terahertz (THz) imaging is a technology that uses electromagnetic waves in the terahertz frequency range, typically between 0.1 and 10 THz, to create high-resolution images of objects. This imaging technique is non-ionizing and can penetrate various materials, including clothing, paper, plastic, and ceramics, while also providing information about the materials being imaged. THz imaging has various applications like medical imaging, agriculture, and security.
