    Abstract: A near-infinity image display system (10) has a convex-faceplate cathode ray tube (12) positioned with respect to a concave mirror (14) such that the cathode ray tube (12) is in front of the center of curvature (16) of the mirror (14) and so that the mirror (14) reflects a near-infinity image of the visual display surface to an eyepoint (20) of an observer located below and in front of the center of curvature (16) of the mirror (14) and below the cathode ray tube (12). The cathode ray tube (12) is positioned at a height above the eyepoint (20) of the observer so that it does not interrupt the vertical field of view (24) of the image reflected to the eyepoint (20) of an observer. The concave mirror (12) may be a spherical, ellipsoidal or toroidal mirror. A multiple-display system (30) may be used to create a mosaic reflected image. In the multiple-display system (30), the convex faceplates of cathode ray tubes (12) are placed side by side, and optimally spaced apart at an angle (35) to provide a near-infinity mosaic reflection to an eyepoint (20) of a single observer or eyepoints (40) and (42) of multiple observers. In the multiple-display system (30), multiple observers are spaced apart a distance (41) that optimizes independent viewing of the near-infinity image by each observer.

    Abstract: Système de visualisation d'image dans l'infini proche (10) comportant un tube à rayon cathodique (12) à face convexe positionné par rapport à un miroir concave (14), de telle sorte que ledit tube (12) soit face au centre de courbure (16) du miroir (14) et que le miroir (14) reflète une image dans l'infini proche de la surface d'affichage visuel vers l'oeil (20) de l'observateur, installé au-dessous et en face du centre de courbure (16) du miroir (14) et au-dessous du tube à rayon cathodique (12). Ledit tube (12) est placé au-dessus de l'oeil (20) de l'observateur de telle sorte qu'il ne coupe pas le champ de vision vertical (24) de l'image reflétée vers l'oeil (20) de l'observateur. Le miroir concave (12) peut être sphérique, ellipsoïdal ou toroïdal. Un système d'affichage multiple (30) peut être utilisé, pour créer une mosaïque de réflexion d'images. Avec ce système à affichage multiple (30), les faces convexes des rayons cathodiques (12) sont placées côte à côte, avec, de préférence, un certain décalage angulaire (35) pour obtenir une réflexion en mosaïque dans l'infini proche pour l'oeil (20) de l'observateur ou pour les yeux (40) de plusieurs observateurs (42). Avec le système à affichage multiple (30), les observateurs sont espacés les uns des autres à une distance (41) procurant à chacun une visualisation indépendante optimale de l'image dans l'infini proche.
