Description

SYSTEME BINOCULAIRE FORME DE DEUX MIROIRS ASPHERIQUES ET ENSEMBLE D ' UN TELBINOCULAR SYSTEM FORMED BY TWO ASPHERIC MIRRORS AND ASSEMBLY OF SUCH
SYSTEM ET D' UN TERMINAL PORTABLESYSTEM AND PORTABLE TERMINAL
L'invention concerne un binoculaire destiné à projeter un plan objet à 5 l'infini, plan objet qui peut être celui d'un micromoniteur ou d'un microécran LCD, dans le but, pour un opérateur, par exemple de visualiser l'image d'une scène en même temps dans le spectre visible et dans le spectre infrarouge à l'aide d'une caméra thermique, mais aussi de pouvoir visualiser par superposition l'image d'une scène et une toute autre image, 0 par exemple une image symbolique.The invention relates to a binocular designed to project an object plane to infinity, an object plane which may be that of a micromonitor or an LCD micro-screen, with the aim, for an operator, for example of viewing the image. of a scene at the same time in the visible spectrum and in the infrared spectrum using a thermal camera, but also to be able to visualize by superimposition the image of a scene and a completely different image, 0 for example a symbolic image.
On utilise de tels binoculaires sur des jumelles d'observation, lunettes de tir, viseurs de casque, viseurs de conduite de tir, viseur TV pour pilote d'avion et même, dans le domaine purement civil, sur des casques pour jeux vidéo 5 ainsi que sur des balladeurs à image et, plus généralement, pour tout système de restitution et/ou d'incrustation d'images par casque avec superposition, ou non, d'images directes.Such binoculars are used on observation binoculars, riflescopes, helmet sights, fire control sights, TV sight for airplane pilots and even, in the purely civil field, on headsets for video games 5 as well than on image walkmans and, more generally, for any system of restitution and / or inlay of images by headphones with superposition, or not, of direct images.
On notera qu'un binoculaire, à deux systèmes optiques respectivement pour 0 les deux yeux, se distingue d'un système bioculaire, comme par exemple une loupe, qui ne comporte qu'une seule optique pour les deux yeux.It will be noted that a binocular, with two optical systems respectively for 0 the two eyes, is distinguished from a biocular system, such as for example a magnifying glass, which has only one optic for the two eyes.
On connaît des binoculaires à deux optiques identiques centrées sur les deux axes des deux yeux, mais ils nécessitent deux objets identiques, ce qui 5 double le prix.Binoculars with two identical optics are known which are centered on the two axes of the two eyes, but they require two identical objects, which doubles the price.
On connaît aussi des binoculaires à deux optiques et recombinaison des faisceaux par prismes ou miroirs, avec ou sans réglage d'écart d'oeil, avec donc un seul objet, mais ces systèmes restent encore trop complexes. 0Binoculars with two optics and recombination of the beams by prisms or mirrors are also known, with or without adjustment of eye gap, with therefore a single object, but these systems are still too complex. 0
La présente invention vise à proposer un binoculaire simple, léger, compact, achromatique et de faible coût.The present invention aims to provide a simple, light, compact, achromatic and low-cost binocular.
A cet effet, l'invention concerne tout d'abord un système binoculaire pour 5 projeter un plan objet à une distance prédéterminée, caractérisé par le fait qu'il comporte deux miroirs asphériques identiques inclinés et montés symétriquement par rapport à un plan.To this end, the invention firstly relates to a binocular system for projecting an object plane at a predetermined distance, characterized by the fact that it comprises two identical aspherical mirrors inclined and mounted symmetrically with respect to a plane.
Le système de l'invention est simple et léger puisqu'il ne comporte qu'un dioptre par oeil.The system of the invention is simple and light since it only has one diopter per eye.
Dans une forme de réalisation particulière, le système peut comporter deux renvois d'angle associés respectivement aux deux miroirs, ce qui est préférable quand le plan objet est défini par un micromoniteur, beaucoup plus encombrant qu'un microécran LCD.In a particular embodiment, the system can comprise two angle references associated respectively with the two mirrors, which is preferable when the object plane is defined by a micromonitor, much more cumbersome than an LCD micro-screen.
Compte tenu du développement de l'informatique, des réseaux de données et des réseaux de communication, la demanderesse propose aussi ici un ensemble d'un terminal de traitement de données portable et d'un système binoculaire de l'invention, dont le plan objet est défini par un écran relié au terminal pour saisir des données d'image reçues par le terminal.Given the development of data processing, data networks and communication networks, the applicant also here proposes a set of a portable data processing terminal and a binocular system of the invention, including the object plane is defined by a screen connected to the terminal for entering image data received by the terminal.
Par terminal portable, il faut comprendre un terminal léger et adapté pour être tenu dans une main et glissé soit dans une poche de vêtement, soit dans une saccoche.By portable terminal, it is necessary to understand a light terminal and adapted to be held in one hand and slipped either in a pocket of clothing, or in a bag.
Comme terminal portable, on peut envisager un ordinateur personnel portable ou un terminal de radiotéléphonie cellulaire, pour, par exemple, une meilleure exploitation en temps réel de données de navigation routière ou, même, dans un souci de confidentialité, d'informations à visualiser mais à soustraire à la vue des tiers.As a portable terminal, it is possible to envisage a portable personal computer or a cellular radiotelephony terminal, for, for example, better use in real time of road navigation data or, even, for the sake of confidentiality, of information to be viewed but to be hidden from view by third parties.
L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation préférée et d'une variante d'un ensemble d'un terminal de traitement de données portable et du système binoculaire de l'invention, en référence au dessin annexé, sur lequelThe invention will be better understood using the following description of a preferred embodiment and of a variant of an assembly of a portable data processing terminal and of the binocular system of the invention, with reference in the accompanying drawing, on which
- la figure 1 est une vue de dessus schématique en coupe de la forme préférée de réalisation de ce dernier, relié à un combiné GSM, etFIG. 1 is a schematic top view in section of the preferred embodiment of the latter, connected to a GSM handset, and
- la figure 2 est une vue en perspective illustrant la variante. Le système binoculaire représenté sur la figure 1 permet de projeter à une distance prédéterminée un plan objet dans lequel on a placé un écran 1, dans cet exemple un écran à cristaux liquides LCD, permettant d'afficher par exemple l'image d'une scène captée par une caméra de prise de vues associée et/ou d'y incruster éventuellement des symboles et autres informations. Deux miroirs 5 identiques, asphériques, sont inclinés et montés symétriquement par rapport à l'axe de la figure 1 représentant un plan médian 10 de symétrie du système, l'écran 1 d'affichage étant centré sur le plan 10 perpendiculairement à celui-ci.- Figure 2 is a perspective view illustrating the variant. The binocular system represented in FIG. 1 makes it possible to project at a predetermined distance an object plane in which a screen 1 has been placed, in this example an LCD liquid crystal screen, making it possible to display for example the image of a scene. captured by an associated camera and / or possibly embed symbols and other information. Two identical, aspherical mirrors 5 are inclined and mounted symmetrically with respect to the axis of FIG. 1 representing a median plane 10 of symmetry of the system, the display screen 1 being centered on the plane 10 perpendicular thereto .
On peut aussi, par des miroirs 5 alors semi-transparents, éventuellement dichroïques, superposer l'image réelle de la scène captée, illustrée par les faisceaux 7, et une image IR de la caméra.It is also possible, by mirrors 5 then semi-transparent, possibly dichroic, to superimpose the real image of the captured scene, illustrated by the beams 7, and an IR image of the camera.
Le plan de coupe, dit horizontal pour la commodité de l'exposé, traverse l'écran 1 et les miroirs 5 sensiblement à mi-hauteur de ceux-ci. On conçoit bien évidemment que le choix ici d'un plan de coupe horizontal et d'un plan médian 10 de symétrie vertical a pour seul but de simplifier l'exposé et que le système de l'invention conserve ses propriétés quelle que soit son orientation.The cutting plane, said to be horizontal for the convenience of the presentation, crosses the screen 1 and the mirrors 5 substantially at mid-height thereof. It is obviously understood that the choice here of a horizontal section plane and a median plane 10 of vertical symmetry has the sole purpose of simplifying the presentation and that the system of the invention retains its properties whatever its orientation .
Les références 2 désignent les yeux d'un observateur portant un casque sur lequel est monté le système. Il pourrait s'agir par exemple d'un pilote d'hélicoptère dont le casque porterait, solidaire du système binoculaire, une caméra infrarouge remplaçant le combiné GSM 9 et commandant l'écran 1 pour former un viseur tête haute.References 2 designate the eyes of an observer wearing a helmet on which the system is mounted. It could for example be a helicopter pilot whose helmet would carry, integral with the binocular system, an infrared camera replacing the GSM handset 9 and controlling the screen 1 to form a head-up viewfinder.
Sur la figure 1, on a représenté trois points quelconques ou pixels du plan objet de l'écran 1, d'où partent trois paires respectives de faisceaux de rayons divergents 3, chaque faisceau de chaque paire atteignant un miroir 5 particulier et y étant réfléchi sous la forme d'un faisceau de rayons ici parallèles 4. Les trois faisceaux 4 de chaque miroir 5 se coupent au niveau de l'oeil 2 associé. L'observateur peut balayer l'écran 1, dans le plan horizontal de la figure, en ayant constamment une image nette, ici à l'infini, de l'écran 1. Chacune des trois positions des faisceaux 3, 4 de chaque miroir 5 illustre une position particulière d'une telle exploration visuelle du champ observable.In FIG. 1, there are shown any three points or pixels of the object plane of the screen 1, from which three respective pairs of beams of divergent rays 3 depart, each beam of each pair reaching a particular mirror 5 and being reflected therein in the form of a beam of rays here parallel 4. The three beams 4 of each mirror 5 intersect at the level of the associated eye 2. The observer can scan the screen 1, in the horizontal plane of the figure, constantly having a clear image, here at infinity, of the screen 1. Each of the three positions of the beams 3, 4 of each mirror 5 illustrates a particular position of such a visual exploration of the observable field.
La forme des miroirs 5, du genre d'une surface sphérique de révolution utilisée hors d'axe, est telle qu'un balayage vertical de l'écran 1, donc en sortant du plan de la figure 1, conserve de même les propriétés optiques ci- dessus, d'image objet à l'infini. Ainsi, pour chaque oeil 2, un élément optique unique (5), hors d'axe, monobloc, remplit à lui seul la fonction voulue de renvoi du plan objet à une distance prédéterminée située dans la plage d'accomodation de l'oeil humain, c'est-à-dire d'environ 25 cm à l'infini.The shape of the mirrors 5, of the kind of a spherical surface of revolution used off-axis, is such that a vertical scan of the screen 1, therefore leaving the plane of FIG. 1, likewise retains the optical properties above, from object image to infinity. Thus, for each eye 2, a single optical element (5), off-axis, monobloc, alone fulfills the desired function of returning the object plane to a predetermined distance located within the accommodation range of the human eye. , i.e. about 25 cm to infinity.
Sur la figure 1 ont été esquissés, en tirets, deux miroirs 6 de renvoi à 90° des deux ensembles de faisceaux 4, en vue d'expliquer la variante de la figure 2.In FIG. 1 have been sketched, in dashed lines, two mirrors 6 for 90 ° deflection of the two sets of beams 4, in order to explain the variant of FIG. 2.
Dans cette dernière, les miroirs 5 de la figure 1 ont basculé de sensiblement 90° vers le bas autour d'un axe fictif s'étendant dans le plan de la figure 1 et passant par les deux miroirs de renvoi 6 et l'écran image associé a pivoté autour du même axe pour occuper une position haute, qui pourrait être bien au-dessus de celle représentée. Les éléments homologues de la figure 1 ont conservé leurs références.In the latter, the mirrors 5 in FIG. 1 have tilted substantially 90 ° downwards around a fictitious axis extending in the plane of FIG. 1 and passing through the two deflection mirrors 6 and the image screen. partner has pivoted around the same axis to occupy a high position, which could be well above that shown. The homologous elements of FIG. 1 have kept their references.
Une configuration de ce type permet de remplacer l'écran LCD 1, monté à hauteur des yeux 2, par un micromoniteur 11, plus performant mais trop encombrant. L'écran du moniteur 11, occupant une position haute, est donc tourné vers le bas, et ici horizontal. Les faisceaux descendants 3 qu'il émet sont donc sensiblement verticaux et sont réfléchis, sous forme de deux ensembles de faisceaux ascendants 41 à rayons parallèles, par les deux miroirs asphériques 5 respectifs tournés vers le haut. Les deux ensembles de faisceaux 41 se réfléchissent sur les deux miroirs de renvoi 6 respectifs, ici plans, pour former les deux ensembles de faisceaux 4 du plan dit horizontal.A configuration of this type makes it possible to replace the LCD screen 1, mounted at eye level 2, with a micromonitor 11, more efficient but too bulky. The screen of the monitor 11, occupying a high position, is therefore turned downwards, and here horizontal. The descending beams 3 which it emits are therefore substantially vertical and are reflected, in the form of two sets of ascending beams 41 with parallel rays, by the two respective aspherical mirrors 5 facing upwards. The two sets of beams 41 are reflected on the two respective deflection mirrors 6, here planes, to form the two sets of beams 4 of the so-called horizontal plane.
Les miroirs de renvoi 6, sont de préférence disposés à distance maximale des miroirs asphériques 5, c'est-à-dire qu'ils peuvent alors être de taille réduite tout en couvrant l'ouverture angulaire voulue (taille angulaire de l'écran) puisque le plan image (yeux 2) est alors proche des miroirs de renvoi 6.The return mirrors 6 are preferably placed at a maximum distance from the aspherical mirrors 5, that is to say that they can then be of size reduced while covering the desired angular opening (angular size of the screen) since the image plane (eyes 2) is then close to the reflecting mirrors 6.
Dans encore une autre variante, non représentée, les miroirs de renvoi 6 sont disposés sur les trajets des faisceaux 3, c'est-à-dire que les miroirs asphériques 5 conservent la position de la figure 1 et que seul l'écran 1 (ou un moniteur 11) a basculé de 90° environ.In yet another variant, not shown, the return mirrors 6 are arranged on the paths of the beams 3, that is to say that the aspherical mirrors 5 retain the position of FIG. 1 and that only the screen 1 ( or a monitor 11) has tilted approximately 90 °.
Par ailleurs, dans tous les exemples de réalisation ci-dessus, il peut être prévu que le plan objet ne soit pas projeté à l'infini, mais simplement à une distance finie, comprise dans la plage d'accomodation des yeux 2, c'est-à- dire par exemple de 25 centimètres à l'infini.Furthermore, in all of the above embodiments, it can be provided that the object plane is not projected to infinity, but simply at a finite distance, included in the range of accommodation of the eyes 2, c ' that is to say, from 25 centimeters to infinity.
En pareil cas, les miroirs 5, et/ou le cas échéant les miroirs de renvoi 6, présentent la forme voulue pour que chaque faisceau 4 quelconque ne soit plus à rayons parallèles mais au contraire à rayons divergeants provenant du plan objet projeté à distance finie. Ainsi, d'une façon générale, le plan objet de l'écran 1, 11 est projeté à une distance accrue par rapport aux yeux 2 pour que l'observateur puisse le voir avec netteté.In such a case, the mirrors 5, and / or where appropriate the deflection mirrors 6, have the desired shape so that each beam 4 of any kind is no longer with parallel rays but on the contrary with diverging rays coming from the object plane projected at a finite distance . Thus, in general, the object plane of the screen 1, 11 is projected at an increased distance from the eyes 2 so that the observer can see it clearly.
Comme évoqué au début, le système binoculaire de l'invention peut servir à la visualisation de tout type d'informations comme par exemple des images de synthèse ou des symboles ou caractères représentant des données. En particulier, comme représenté, il peut être prévu un ensemble constitué d'un terminal de traitement de données portable et du système binoculaire selon l'invention, dont l'écran, disposé au niveau du plan objet, est relié au terminal pour saisir des données d'image reçues ou engendrées par le terminal. Il peut par exemple s'agir du terminal de radiotéléphonie cellulaire 9 ou encore d'un ordinateur personnel portable. On peut alors afficher en temps réel des données de navigation routière ou bien ainsi prendre connaissance de données confidentielles. On peut en particulier visualiser des pages d'informations HTML provenant d'un réseau informatique du genre de l'Internet et des menus d'exploitation d'applications diverses traitées par le terminal. As mentioned at the beginning, the binocular system of the invention can be used for the visualization of any type of information such as for example synthetic images or symbols or characters representing data.
