VERFAHREN ZUR ERZEUGUNG VON LICHT EINES GEGEBENEN POLARISATIONSZUSTANDES

摘要

A method and apparatus or configuration generates light of a given polarization state (P). A polarization state-sensitive beam splitter is acted upon by light (L) at an input (E₁), light (L_P) of the given polarization state being output by the beam splitter ( 1 ) at a first beam splitter output (A₁). Light (L_S) with polarization state (S) that is perpendicular to the given state (P) is changed with respect to this state and also output. The light of the changed polarization state again acts upon the polarization state-sensitive beam splitter at the input (E₁). The apparatus or configuration achieves this by having the optic input (E₃) of a polarization state-changing structural element whose optic output (A₃) is operationally connected to the optic input (E₁) of the polarization state-sensitive beam splitter, operationally connected to the second optic output (A₂).
