摘要： A time-multiplexed stereoscopic 3d projection system including a beam-splitting element to split the randomly polarized image-beam generated by a single-lens projector into one primary image-beam, possessing a first state of linear polarization, and two secondary image-beams, both possessing a second state of linear polarization. The polarization states are mutually orthogonal. The primary and secondary image-beams recombine to form a complete image on the surface of a polarization-preserving projection-screen. There are polarization modulators that modulate the first and second states of linear polarization between a left and right circular polarization state. There is a contrast enhancement film in the optical-path of the primary or secondary image-beams located between the polarization modulator and the projection-screen. The contrast enhancement film comprises a stack of at least three uniaxially stretched retardation-films which perturb the circular polarization state of said image-beams and which possess an in-plane retardation value substantially equal to 140 nm, 270 nm, or 540 nm.

The arrangement (130) comprises at least two chiral objects (124), wherein the chiral objects (124) are closely located with respect to each other. Herein, a first chiral object (126) is additionally designed for scattering and/or absorbing only a first polarization handedness of an incident electromagnetic field (110) in a manner that an electromagnetic field scattered by the first chiral object (126) only comprises the first polarization handedness and, further, for being transparent to a second polarization handedness of the incident electromagnetic field (110), wherein a second chiral object (128) is additionally designed for scattering and/or absorbing only the second polarization handedness of the incident electromagnetic field (110) in a manner that an electromagnetic field scattered by the second chiral object (128) only comprises the second polarization handedness and, further, for being transparent to the first polarization handedness of the incident electromagnetic field (110). Herein, the first polarization handedness and the second polarization handedness comprise an opposite sign.
Further, a system (148) comprising at least two pluralities of chiral objects (124) of the mentioned kind and its use as part of a viewing apparatus for three-dimensional images, wherein the three-dimensional images are encoded in two opposite circular polarizations, is disclosed.
