The invention relates to a display comprising an optical imager () for shaping light beams emitted by a light beam generator system (), said beams being introduced into said imager via an inlet face, and for directing the beams towards the eye (O) of a wearer in order to enable an image (I) to be viewed, two hooks () being in reference positions relative to the imager, and said light beam generator system including a connection arrangement for connection to said hooks (), the connection between said system and said hooks being releasable and said hooks () being designed to be received in housings carried by the connection arrangement. According to the invention, said housings are arranged in such a manner that said connection arrangement is assembled on said hooks by applying thrust against one of said hooks (), by turning about said hook, and by snap-fastening onto the other hook ().

Display for incorporating in a pair of eyeglasses

The present invention relates to a display system for stereoscopic viewing, the system comprising a binocular viewing device, information content, and a display source. The display system is remarkable in that it further comprises electronic components for implementing pieces of software for optimizing the binocular viewing device, the information content, and the display source, said pieces of optimization software together forming a loop for managing various parameters. The wearer of said device can thus view the information content via the binocular viewing device under conditions that are best adapted to the wearer's physiology.

An electronic display arrangement for taking light signals forming an image emitted from a miniature screen () and referred to as a screen image, and for conveying them to the eye (O) of a user to enable a virtual image (I) to be viewed, the arrangement having a miniature screen control device having an arrangement for subdividing a source image into N screen images (I) and in that it includes a mosaicing device () having an exit viewport () and serving to convey the N screen images in a manner in which they are spatially offset from one another and time shifted from one another at a period (&#x3c4;) shorter than the remanence time of the retina of the eye divided by N, each screen image (I) being conveyed towards the eye of the wearer for viewing a virtual sub-image (I), the N resulting and adjacent virtual sub-images together forming said virtual image (I) in full, said mosaicing device () being constituted by a light polarization control element () and by an element () for spatially reconstructing the virtual image (I). A mosaicing device has a light pipe () of material that is transparent in the visible domain and said light pipe is disposed between said control element () and said element for spatially reconstructing the virtual image.

Opto-electronic display assembly

A light pipe is provided for transmitting light signals from one of its ends to its other end facing toward the eye of a user for viewing a virtual image. The light pipe includes a diffractive component formed directly in the inlet surface. The diffractive component is an element satisfying the equation of an aspherical component of revolution of the 'kinoform' type, where the diffractive component of the pipe has power situated in a range D (Thresh, X) defined by D(Thresh, X)=D(Thresh) INTERSECTION D(X).

Optical pipe intended for producing an electronic display arrangement

The invention relates to an ophthalmic lens for constituting an ophthalmic display, associated with an optical imager for shaping light beams and directing them towards the eye of the wearer so as to enable information content to be viewed, said optical imager being secured to said lens. According to the invention, the lens is associated with marking including referencing for the position of said imager relative to said lens as a function of the correction parameters of said lens.

Ophthalmic lens and a display including such a lens and an optical imager

The invention relates to a display () for mounting on a pair of eyeglasses (), the display comprising an electronic and optical system for generating light beams (A) and an imager (B) for shaping the light beams coming therefrom, the display including a releasable securing arrangement for releasably securing it on the pair of eyeglasses, and an adjustment arrangement for adjusting the position of said imager relative to the eye of the wearer. According to the invention, the display comprises two elements, a first element () carrying said removable securing arrangement, and a second element () including said electronic and optical system and said imager, and connectable to said first element via said adjustment arrangement for adjusting the pupillary distance and including position-locking means for locking it in the adjusted position.

Polarization splitter, method of manufacturing same and ophthalmic lens incorporating projection inserts containing it

An ophthalmic lens contains inserts () for projecting an image towards the user's eye. The lens is treated by coating the surface order to attenuate light reflected on the treated surface from the inside of the lens. Coating the surface of the lens attenuates the parasitic images formed by rays reflected on the coated surface and projected by the insert.
