Teraphysics Gets Contract for Terahertz Threat Detection System

Facebook X LinkedIn Email
Teraphysics Corp. of Cleveland, a developer of compact devices that operate in the terahertz band of the spectrum, has received a $730,000 Phase II Small Business Innovation Research (SBIR) contract from the Army Research Office to develop technology to enable new capabilities in threat detection systems. "The technology developed in this contract will enable a new class of systems for detection of hidden weapons, explosives and contraband for military and homeland security applications," said Jim Dayton, chief technology officer for Teraphysics and principal investigator on the contract....Read full article

    frequency
    With reference to electromagnetic radiation, the number of crests of waves that pass a fixed point in a given unit of time, in light or other wave motion. Expressed in hertz or cycles per second.
    nanotechnology
    The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
    spectrum
    See optical spectrum; visible spectrum.
    terahertz
    Terahertz (THz) refers to a unit of frequency in the electromagnetic spectrum, denoting waves with frequencies between 0.1 and 10 terahertz. One terahertz is equivalent to one trillion hertz, or cycles per second. The terahertz frequency range falls between the microwave and infrared regions of the electromagnetic spectrum. Key points about terahertz include: Frequency range: The terahertz range spans from approximately 0.1 terahertz (100 gigahertz) to 10 terahertz. This corresponds to...
    wave
    1. An undulation or vibration; a form of movement by which all radiant energy of the electromagnetic spectrum is estimated to travel. 2. A type of surface defect, usually due to improper polishing.
