Compensation of the phase anisotropy of an oblique mirror in visible light

Abstract

The state of polarization of an oblique incident wave is modified by a reflexion on a metallic mirror, because of the inequality of the phases of the reflexion coefficients for polarization parallel and perpendiculer to the incidence plane. We show, that it is possible to the compensat in white light, the phase anisotrophy of certain mirrors by the aid of a cristallin plate. Different incidence angles are considered and the field of the compensated mirror is studied. Application to optical microsophy is particularly interesting.
