Holographic device for formation of colored, polarized and angularly separated light beams and video image projector which utilizes it
A holographic device, which has first and second roughly coplanar and superposed holograms, which are illuminated by the same non-polarized light beam with at least first and second spectral compositions, the holograms each being recorded in a manner such that in its middle, the axis of the diffract...

| Zusammenfassung: | A holographic device, which has first and second roughly coplanar and superposed holograms, which are illuminated by the same non-polarized light beam with at least first and second spectral compositions, the holograms each being recorded in a manner such that in its middle, the axis of the diffracted beam is perpendicular to the direction of the incident beam in this medium, the diffracted beams forming first and second angularly separated light beam with the same polarization, and having different spectral compositions. |
