A new twist on an old technology clears the way for new applications.

Dr. Brian J. Soller and Trevor Rice, Luna Innovations Inc.

Optical fibers make ideal physical sensors. Light, rugged and immune to interference from stray electrical signals, they respond to a variety of external stimuli – qualities that have spawned extensive efforts to use them for measuring, or “sensing,” physical attributes such as temperature, strain and pressure. They are used for temperature monitoring in oil and gas “down hole” and applications, strain and fatigue monitoring in civil structures (dams, bridges) and buildings, strain measurement in composite structures and intrusion monitoring in security applications. Fiber sensors...Read full article

    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
