Our core technologies of silicon and III-V semiconductor fabrication give us the unique ability to provide components, sub-systems and systems for baggage, portal (people) and package scanning for both currently available based systems and work with our partners on the next generation systems based on our patented terahertz technologies.
Silicon based materials can be use to detect x-rays when used in conjunction with a scintillator. The general description of a scintillator is a material that emits low-energy photons when struck by a high-energy charged particle. When used as a gamma-ray detector, the scintillator does not directly detect the gamma rays. Instead, the gamma rays produce charged particles in the scintillator crystals, which interact with the crystal and emit photons. It is the photons that the silicon based detectors can “see” or detect.
Terahertz radiation (THz) consist of the band of electromagnetic radiation between the microwave and infrared portions of the spectrum. Terahertz offers a highly accurate, safe and rapid way of conducting material inspection, moisture sensing, spectroscopy and imaging.
Until recently, practical sources and detectors working in this frequency range have not been commercially available. Now, for the first time, a Terahertz instrument is available in a rugged, easy-to-use system…the T-Ray™ 2000 Analytical System. This system is designed for application research and development and can be customized for high-speed, non-laboratory applications.
