  2. Bragg's law - Wikipedia

    en.wikipedia.org/wiki/Bragg's_law

    Bragg's law. Physical law regarding scattering angles of radiation through a medium. In many areas of science, Bragg's law, Wulff –Bragg's condition, or Laue–Bragg interference are a special case of Laue diffraction, giving the angles for coherent scattering of waves from a large crystal lattice. It describes how the superposition of wave ...

  3. Bragg peak - Wikipedia

    en.wikipedia.org/wiki/Bragg_peak

    Bragg peak. The Bragg curve of 5.49 MeV alphas in air has its peak to the right and is skewed to the left, unlike the x-ray beam below. The Bragg peak is a pronounced peak on the Bragg curve which plots the energy loss of ionizing radiation during its travel through matter. For protons, α-rays, and other ion rays, the peak occurs immediately ...

  4. Bragg plane - Wikipedia

    en.wikipedia.org/wiki/Bragg_plane

    Bragg plane. In physics, a Bragg plane is a plane in reciprocal space which bisects a reciprocal lattice vector, , at right angles. [1] The Bragg plane is defined as part of the Von Laue condition for diffraction peaks in x-ray diffraction crystallography. Considering the adjacent diagram, the arriving x-ray plane wave is defined by:

  5. Acousto-optic modulator - Wikipedia

    en.wikipedia.org/wiki/Acousto-optic_modulator

    An acousto-optic modulator (AOM), also called a Bragg cell or an acousto-optic deflector (AOD), uses the acousto-optic effect to diffract and shift the frequency of light using sound waves (usually at radio-frequency). They are used in lasers for Q-switching, telecommunications for signal modulation, and in spectroscopy for frequency control.

  6. Dynamical theory of diffraction - Wikipedia

    en.wikipedia.org/wiki/Dynamical_theory_of...

    The dynamical theory of diffraction considers the wave field in the periodic potential of the crystal and takes into account all multiple scattering effects. Unlike the kinematic theory of diffraction which describes the approximate position of Bragg or Laue diffraction peaks in reciprocal space, dynamical theory corrects for refraction, shape ...

  7. Distributed Bragg reflector - Wikipedia

    en.wikipedia.org/wiki/Distributed_Bragg_reflector

    Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...
