//ˈtiːˌɹeɪ// noun

Noun

1
An electromagnetic wave with a frequency intermediate between, and sharing the properties of, short radio waves and long infrared waves, generally in the 0.1 to 10 terahertz (THz) band of frequencies. also, attributive, in-plural
"This terahertz "T-ray" technology combines imaging, real-time acquisition of terahertz waveforms and advanced signal processing techniques to obtain far-infrared images of objects and materials. In many cases, T-Ray^([sic]) images can also distinguish chemical compositions of the object. These features of T-ray imaging have generated interest in commercial applications in diverse areas as moisture analysis, quality control of plastic parts, packaging inspection, and trace gas analysis and monitoring."

Initialism of t(erahertz) + ray, modelled after X-ray. The term was coined in Bell Labs in the United States in the mid-1990s.
