Photon Control Awarded Fiber-Optic Sensing Patent

Facebook X LinkedIn Email
Photonic sensor developer Photon Control Inc. of Burnaby, British Columbia, announced it has been granted US Patent No. 7,099,015 for fiber-optic sensing. The patent protects interferometric technology for sensing physical parameters, such as pressure and temperature. Photon said it will use the patent in instrumentation for heavy oil production (downhole pressure and temperature monitoring), and sensing for the power industry, among other applications. Photon's interferometric technology is based on white-light interferometry, a method which requires sending a wide spectrum of light (white...Read full article

    Glossary
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photon
    A quantum of electromagnetic energy of a single mode; i.e., a single wavelength, direction and polarization. As a unit of energy, each photon equals hn, h being Planck's constant and n, the frequency of the propagating electromagnetic wave. The momentum of the photon in the direction of propagation is hn/c, c being the speed of light.
    photonics
    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...
    spectrometer
    A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.
    white light
    Light perceived as achromatic, that is, without hue.
