  • T-Ray Science Licenses MIT THz Patents
Oct 2008
Vancouver-based TeraHertz radiation researcher T-Ray Science Inc. today announced it has signed an exclusive patent license agreement with the Massachusetts Institute of Technology in Cambridge, Mass., to produce spectroscopy and imaging systems that use dual-mode, pulsed and continuous terahertz (THz) waves. Noninvasive THz radiation lies between the infrared and microwave range of the electromagnetic spectrum. The new system is the first to integrate both pulsed and continuous wave spectroscopic analysis and imaging, allowing the user to use a pulsed THz radiation generation mode to quickly find the portion of the THz spectrum where the absorption signature of the material being tested is located, T-Ray said. After that, one can switch to the continuous wave THz radiation generation mode to perform a high-resolution scan over a small range of frequency around the absorption frequency determined by the pulsed THz system. The global spectroscopy market, valued at approximately $5.2 billion, is currently dominated by single-mode systems, T-Ray said, but market research has indicated a strong trend towards the use of dual-mode devices that could revolutionize the industry.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
The emission and/or propagation of energy through space or through a medium in the form of either waves or corpuscular emission.
