A new interferometric technique precisely analyzes optical vector fields by reconstructing polarization singularities. This method fully characterizes s contours and C points in complex light fields.

Area of Science:

  • Optics and Photonics
  • Mathematical Physics

Background:

  • Optical vector fields contain singularities like C points and s contours.
  • Analyzing these singularities is crucial for understanding light polarization.
  • Existing methods may lack completeness in characterizing these features.

Purpose of the Study:

  • To develop and present a novel interferometric technique.
  • To enable comprehensive analysis of the polarization singular skeleton.
  • To demonstrate the technique's applicability to complex optical fields.

Main Methods:

  • Elaboration of an interferometric method for optical vector field analysis.
  • Reconstruction of polarization singularities (s contours and C points) from interferometric data.
  • Application of the technique to randomly polarized speckle-fields.
