Interferometric visibility

The interference contrast describes the visibility (contrast) of an interference phenomenon quantitatively. It is defined as the ratio of the intensities of two successive maxima and minima:

  • The optimal value is 1, in the case of total unrecognizable the interference phenomenon he is 0
  • This definition assumes that the average intensity is Geich. Then the amplitude of the intensity is the same. Because of these assumptions.
  • In the case of interference of light is usually dependent on the source coherence length of the restricting factor.

The interference contrast is important in particular for interferometry, holography and phase contrast microscopy.
