词汇 birefringent
释义

Definition of birefringent in English:

birefringent

adjectiveˌbʌɪrɪˈfrɪn(d)ʒ(ə)ntˌbaɪrəˈfrɪndʒənt
Physics
  • Having two different refractive indices.

    〔物理〕双折射的

    Example sentencesExamples
    • The model appeared to require that a gas of hydrogenic atoms would be magnetically birefringent, because the electron would orbit in a plane perpendicular to the field direction.
    • At the macroscopic scale, samples held in test-tubes spontaneously demix under the influence of gravity into a top isotropic phase and a bottom birefringent nematic phase.
    • In traditional polarization microscopy and orientational spectroscopy, several techniques have been used to determine birefringent and dichroic properties.
    • When polarization is a concern, linear and birefringent polarizers can be used to remove, reflect, or refract one of the polarization components.
    • A birefringent interference polarizer which may be fabricated from readily available materials using established coextrusion techniques is provided.

Derivatives

  • birefringence

  • noun bʌɪrɪˈfrɪndʒ(ə)nsˌbaɪrəˈfrɪndʒ(ə)ns
    Physics
    • Polarization images probe linear birefringence and can only achieve contrast by having orthogonal polarizers for excitation and collection.
      Example sentencesExamples
      • The use of polarized illumination makes birefringence a factor in optical performance.
      • The chitinized walls that lined many of the spray flow structures exhibited birefringence in polarized light microscopy.
      • They demonstrated diagnostic negative birefringence under the polarizing microscope.
      • Such flexibility has been observed by electrical birefringence, electron paramagnetic resonance, fluorescence resonance energy transfer, phosphorescence, and electron microscopy.
