  2. Polarization mode dispersion - Wikipedia

    en.wikipedia.org/wiki/Polarization_mode_dispersion

    Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. Unless it is compensated, which is difficult, this ultimately ...

  4. Photon Multiplicity Detector - Wikipedia

    en.wikipedia.org/wiki/Photon_Multiplicity_Detector

    A PMD typically consists of two main layers Veto Detector and Preshower Detector. Veto Detector layer is designed to reject charged particles. Photons pass through a converter in Preshower Detector layer, initiating an electromagnetic shower. The detector then measures the number of cells activated by the shower, providing information about the ...

    en.wikipedia.org/wiki/Maxwell's_equations_in...

    This equation is completely coordinate- and metric-independent and says that the electromagnetic flux through a closed two-dimensional surface in spacetime is topological, more precisely, depends only on its homology class (a generalization of the integral form of Gauss law and Maxwell–Faraday equation, as the homology class in Minkowski ...

    PMD Technologies (stylised as pmdtechnologies) is a developer of CMOS semiconductor 3D time-of-flight (ToF) components and a provider of engineering support in the field of digital 3D imaging. [2] The company is named after the Photonic Mixer Device (PMD) technology used in its products to detect 3D data in real time.

  8. Physical medium dependent - Wikipedia

    en.wikipedia.org/wiki/Physical_Medium_Dependent

    The Ethernet PMD sublayer is part of the Ethernet physical layer (PHY). The hierarchy is as follows: Data link layer (Layer 2) Logical link control (LLC) sublayer; Medium access control (MAC) sublayer Reconciliation sublayer (RS) – This sublayer processes PHY local/remote fault messages and handles DDR conversion; PHY layer (Layer 1)
