title: A twisted periscope arrangement for transporting elliptically polarized light without change in its polarization state.
abstract: The authors describe a dual-mirror 90(∘) twisted periscope arrangement for transporting polarized light in air, wherein a general elliptic polarization state of the light is preserved at all wavelengths. It is experimentally demonstrated that in the wavelength range 400-1000 nm, this arrangement preserves the polarization state fairly well when using either metallic or dielectric mirrors.
