Definitions related to microscopy, phase-contrast:
  • (phase contrast microscopy) A microscopic technique in which the amplitude shift that occurs when light passes through a specimen highlights structures or details within the specimen.

  • (phase-contrast microscopy) A simple non-quantitative form of interference microscopy of great utility in visualising live cells. Small differences in optical path length due to differences in refractive index and thickness of structures are visualised as differences in light intensity.

  • (phase contrast microscopy) Form of interference microscopy in which variations of the refracting index in the object are converted into variations of intensity in the image.

  • A form of interference microscopy in which variations of the refracting index in the object are converted into variations of intensity in the image. This is achieved by the action of a phase plate.
