摘要： Certain optical imaging systems exhibit disparate vertical and horizontal image focal surfaces; at least one of which is tipped with respect to the optical axis. The projection optics which illuminates such systems must provide that the vertical image components focus upon the nominal vertical image surface, while the horizontal image components focus on the disparate horizontal image surface. Because at least one of these image surfaces may be tilted with respect to the projection axis, correction is required to maintain focus over the entire image surfaces and to eliminate keystoning. The system may also require differing vertical and horizontal image magnifications as projected upon the above disparate focal surfaces. This invention describes, inter alia, the techniques for meeting these varied requirements, to project a rectilinear object field such that it forms a final focused rectilinear image in a system having tipped and disparate image planes.

摘要： An optical system for displaying an image comprising means for illuminating an object (211) and directing the image light to a display device (205) having an input surface and an output surface. Anamorphic optical means (Ch, Cv) are disposed between the object and the input surface operative to focus one directional component of the image at the input surface and to focus a different directional component of the image at the output surface.

摘要： Dans un systeme stereoscopique pour anaglyphe des images de gauche et de droite sont codees sous forme de franges de couleurs complementaires dans les regions de defocalisation de telle maniere que l'image, lorsqu'on la regarde a travers des lunettes a verre filtre de maniere appropriee, est percue sous forme d'image en couleurs tridimensionnelle mais, lorsqu'on la regarde sans lunettes, elle apparait essentiellement comme une image en couleur normale en deux dimensions. De maniere a ameliorer l'effet tridimensionnel et la compatibilite de l'image bidimensionnelle, un diaphragme special (38) est utilise pour commander la quantite de lumiere passant au travers des lentilles du systeme d'image. Le diaphragme restreint essentiellement la quantite de lumiere dans le sens vertical seulement, gardant ainsi la separation totale gauche-droite puisque la quantite de lumiere passant au travers du filtre est restreinte par le diaphragme. Les filtres (34) de prise de vues du systeme d'image sont choisis de sorte qu'apres le traitement normal la colorimetrie de l'image n'est pas perturbee. Pour cela il faut que les caracteristiques spectrales des photorecepteurs aient les memes rapports avec les filtres et sans les filtres. Les verres a travers lesquels on regarde l'image tridimensionnelle comprennent des moyens de filtrage de couleurs complementaires (figs. 10 et 11) pour les lentilles de gauche et de droite ayant des caracteristiques de luminosite approximativement equilibrees. On ameliore le confort de la personne qui regarde sans degrader sensiblement l'image stereoscopique en limitant la diaphonie entre les lentilles respectives.

摘要： Anaglyph stereoscopic system wherein left and right images are encoded as complementary color fringes in the defocus regions such that the image, when viewed through appropriately filtered glasses, is perceived as a three-dimensional colored image but, when viewed without glasses, appears essentially as a normal two-dimensional colored image. In order to enhance the three-dimensional effect and the compatibility of the two-dimensional image, a special iris (38) is employed for controlling the amount of light passing through the taking lenses of the imaging system. Essentially, the iris restricts the amount of light in the vertical direction only, thereby retaining full left right separation as the amount of light passing through the filter is restricted by the iris. The taking filters (34) of the imaging system are selected so that after normal processing, the image colorimetry is not disturbed. This requires that the spectral characteristics of the photoreceptors maintain the same ratios with the filters as without. The glasses through which the three-dimensional image is viewed includes complementary color filtering means (Figs. 10 and 11) for the left and right lenses of approximately balanced luminosity characteristics. Viewer comfort is materially enhanced without substantial degradation of the stereoscopic image by providing for a limited amount of cross-talk between the respective lenses.
