Chaque lobe lumineux présente ainsi une zone d'éclairage localisée vers le visage de l'individu 102 et lors de la progression de l'individu 102, chaque lobe lumineux s'éteint successivement assurant ainsi un éclairement approprié tout le long du passage 108.  In Figs., The arrows 114a and 114b represent the main direction of illumination which corresponds to the main direction of the light lobe resulting from the transmission. Each light lobe thus has a localized lighting zone towards the face of the individual 102 and during the progression of the individual 102, each lobe light turns off successively thus providing appropriate illumination all along the passageway 108.
La Fig. 2 montre un mode de réalisation particulier de la paroi 106a mais l'autre paroi 106b présente les mêmes caractéristiques.  Fig. 2 shows a particular embodiment of the wall 106a but the other wall 106b has the same characteristics.
La paroi 106a présente une vitre d'éclairage 202 qui s'étend sur une partie de la paroi 106a et qui est disposée de manière à éclairer le visage des individus 102 passant dans le sas 100 au moment de la capture du visage.  The wall 106a has a lighting pane 202 which extends over a portion of the wall 106a and which is arranged to illuminate the faces of the individuals 102 passing through the airlock 100 at the time of the capture of the face.
Les vitres d'éclairage 202 des deux parois 106a et 106b sont en face l'une de l'autre pour assurer une uniformité de l'éclairage des deux côtés du visage de l'individu 102.  The lighting windows 202 of the two walls 106a and 106b face each other to ensure a uniformity of illumination on both sides of the face of the individual 102.
Chaque vitre d'éclairage 202 est constituée d'un matériau transparent du type verre, PMMA (Polyméthacrylate de méthyle) etc., ce qui permet aux équipes de sécurité placées à l'extérieur du sas 100 de surveiller le comportement de l'individu 102 dans le sas 100. Dans ce cas, la surveillance est facilitée si le reste de la paroi 106a est également transparent.  Each lighting pane 202 is made of a transparent material such as glass, PMMA (polymethyl methacrylate) etc., which allows the security teams placed outside the chamber 100 to monitor the behavior of the individual. in the chamber 100. In this case, monitoring is facilitated if the remainder of the wall 106a is also transparent.
Bien sûr, il est possible de prévoir que la vitre d'éclairage 202 couvre entièrement la paroi 106a. Dans ce cas, c'est toute la paroi 106a, 106b qui est transparente. En d'autres termes, la vitre d'éclairage 202 s'étend sur au moins une partie de la paroi 106a et elle est coplanaire avec elle. Of course, it is possible to provide that the lighting pane 202 completely covers the wall 106a. In this case, the entire wall 106a, 106b is transparent. In other words, the lighting pane 202 extends over at least a portion of the wall 106a and is coplanar with it.
La vitre d'éclairage 202 est limitée ici par quatre bords 204a-d.  The lighting pane 202 is here limited by four edges 204a-d.
A chaque bord 204a-d correspond une tranche de la vitre d'éclairage 202 qui s'étend dans l'épaisseur de la vitre d'éclairage 202.  At each edge 204a-d corresponds a slice of the lighting pane 202 which extends in the thickness of the lighting pane 202.
Le long d'au moins l'une des tranches (ici les quatre correspondantes aux quatre bords 204a-d), est disposée une source lumineuse 206a-d qui éclaire la tranche considérée vers l'intérieur de la vitre d'éclairage 202.  Along at least one of the slices (here the four corresponding to the four edges 204a-d) is disposed a light source 206a-d which illuminates the slice considered towards the inside of the lighting pane 202.
Chaque source lumineuse 206a-d prend par exemple la forme d'un tube fluorescent ou d'une barrette de diodes électroluminescentes (DEL).  Each light source 206a-d takes for example the form of a fluorescent tube or a strip of light-emitting diodes (LEDs).
Chaque faisceau lumineux 210 ainsi généré se propage dans l'épaisseur de la vitre d'éclairage 202 qui constitue un guide d'onde pour les faisceaux lumineux 210.  Each light beam 210 thus generated propagates in the thickness of the lighting pane 202 which constitutes a waveguide for the light beams 210.
Les sources lumineuses 206a-d sont choisies de manière à ce que les angles des faisceaux lumineux qu'ils émettent sont tels que lesdits faisceaux lumineux 210 puissent se réfléchir à l'intérieur de la vitre d'éclairage 202 sans qu'ils puissent être transmis vers l'extérieur de la vitre d'éclairage 202 de manière inappropriée.  The light sources 206a-d are chosen so that the angles of the light beams they emit are such that said light beams 210 can be reflected inside the lighting pane 202 without being able to be transmitted. to the outside of the lighting pane 202 improperly.
Pour que les faisceaux lumineux 210 soient transmis de manière appropriée, c'est-à-dire pour qu'ils éclairent le visage de l'individu 102 avec l'angle approprié pour obtenir le meilleur éclairage possible, la vitre d'éclairage 202 présente au moins une zone d'extraction 208, chacune étant destinée à permettre la sortie d'une partie des faisceaux lumineux 114a, 114b de la vitre d'éclairage 202 selon ledit angle.  In order for the light beams 210 to be transmitted in an appropriate manner, that is to say, so that they illuminate the face of the individual 102 with the appropriate angle to obtain the best possible illumination, the lighting pane 202 presents at least one extraction zone 208, each being intended to allow the exit of a portion of the light beams 114a, 114b of the lighting pane 202 at said angle.
De manière optimale, l'angle de sortie des faisceaux lumineux transmis 114a, 114b est de l'ordre de 45° par rapport au plan de la vitre d'éclairage 202 dont ils sont issus et orienté vers l'entrée 110.  Optimally, the output angle of the transmitted light beams 114a, 114b is of the order of 45 ° with respect to the plane of the lighting pane 202 from which they are derived and oriented towards the entry 110.
Mais l'angle de sortie des faisceaux lumineux transmis 1 14a, 1 14b peut être différent selon la géométrie du sas 100. En effet, la largeur et la longueur du sas 100 peuvent varier d'un sas 100 à un autre, et l'angle de sortie des faisceaux lumineux transmis 114a et 114b doit être adapté en fonction de cette géométrie afin d'optimiser l'éclairage de l'individu.  But the output angle of the transmitted light beams 1 14a, 1 14b may be different depending on the geometry of the chamber 100. Indeed, the width and the length of the lock 100 may vary from one lock 100 to another, and the the output angle of transmitted light beams 114a and 114b must be adapted according to this geometry to optimize the lighting of the individual.
L'angle de sortie des faisceaux lumineux transmis 114a, 114b est alors de préférence compris entre 30° et 60°.  The output angle of the transmitted light beams 114a, 114b is then preferably between 30 ° and 60 °.
La Fig. 3 présente un mode de réalisation particulier des zones d'extraction 208. Chaque zone d'extraction 208 comporte une première zone 302 et une deuxième zone 304 qui est disposée sur la face intérieure de la vitre d'éclairage 202 qui est orientée vers le passage 108, c'est-à-dire vers l'intérieur du sas 100. La première zone 302 est disposée sur l'autre face de la vitre d'éclairage 202, c'est-à-dire celle qui est orientée vers l'extérieur du sas 100 et qui constitue la face extérieure de la vitre d'éclairage 202. Fig. 3 shows a particular embodiment of the extraction zones 208. Each extraction zone 208 comprises a first zone 302 and a second zone 304 which is disposed on the inner face of the lighting pane 202 which is oriented to the passage 108, that is to say towards the inside of the lock 100. The first zone 302 is disposed on the other face of the lighting pane 202, that is to say the one which is oriented to the outside of the chamber 100 and which constitutes the outer face of the lighting pane 202.
La première zone 302 comporte des moyens pour modifier les règles de réflexion des faisceaux lumineux 210 à l'intérieur de la vitre d'éclairage 202 sur la face extérieure afin qu'ils soient réfléchis vers la face intérieure et transmis à travers celle- ci. La deuxième zone 304 comporte des moyens pour orienter les faisceaux transmis 114a de la manière appropriée, c'est-à-dire vers le visage de l'individu 102.  The first zone 302 comprises means for modifying the reflection rules of the light beams 210 inside the lighting pane 202 on the outer face so that they are reflected towards the inner face and transmitted therethrough. The second zone 304 includes means for orienting the transmitted beams 114a in the appropriate manner, that is to say towards the face of the individual 102.
A chaque première zone 302 correspond une deuxième zone 304 et elles sont disposées en face l'une de l'autre de part et d'autre de la vitre d'éclairage 202.  Each first zone 302 corresponds to a second zone 304 and is disposed opposite each other on either side of the lighting pane 202.
La première zone 302 peut prendre par exemple la forme d'un patch de peinture diffusante.  The first zone 302 may take for example the form of a diffusing paint patch.
La deuxième zone 304 peut prendre par exemple la forme de prismes, comme par exemple un film polyester ou polycarbonate supportant une structure superficielle rainurée en forme de microprismes à profil symétrique ou asymétrique. La hauteur des microprismes symétriques est par exemple de l'ordre de 100 μπι. L'angle des prismes est choisi pour obtenir l'angle voulu pour les faisceaux transmis 114a.  The second zone 304 may for example take the form of prisms, such as for example a polyester or polycarbonate film supporting a grooved surface structure in the form of microprisms symmetrical or asymmetrical profile. The height of the symmetrical microprisms is for example of the order of 100 μπι. The angle of the prisms is chosen to obtain the desired angle for transmitted beams 114a.
Dans le mode de réalisation de la Fig. 3, les prismes sont accolés sur la vitre d'éclairage 202 par l'intermédiaire de leurs sommets.  In the embodiment of FIG. 3, the prisms are contiguous on the lighting pane 202 through their vertices.
La Fig. 4 présente un autre mode de réalisation particulier des zones d'extraction Fig. 4 shows another particular embodiment of the extraction zones
208. Chaque zone d'extraction 208 présente la forme d'un patch 402 qui est optiquement couplée à la face intérieure de la vitre d'éclairage 202. 208. Each extraction zone 208 has the shape of a patch 402 which is optically coupled to the inner face of the lighting pane 202.
Le patch 402 est destiné à orienter les faisceaux transmis 114a de la manière appropriée. Le patch 402 comporte par exemple des prismes, comme par exemple un film polyester ou polycarbonate supportant une structure superficielle rainurée en forme de microprismes à profil symétrique ou asymétrique. La hauteur des microprismes symétriques est par exemple de l'ordre de 100 μπι. L'angle des prismes est choisi pour obtenir l'angle voulu pour les faisceaux transmis 114a.  The patch 402 is for directing the transmitted beams 114a in the appropriate manner. The patch 402 comprises, for example, prisms, for example a polyester or polycarbonate film supporting a grooved surface structure in the form of microprisms with a symmetrical or asymmetric profile. The height of the symmetrical microprisms is for example of the order of 100 μπι. The angle of the prisms is chosen to obtain the desired angle for transmitted beams 114a.
Dans le mode de réalisation de la Fig. 4, les prismes sont accolés sur la vitre d'éclairage 202 par l'intermédiaire de leurs bases.  In the embodiment of FIG. 4, the prisms are contiguous on the 202 glass pane through their bases.
Chaque patch 402 est fixé sur la vitre d'éclairage 202 par l'intermédiaire d'un moyen de couplage optique comme par exemple du liquide d'indice ou d'un adhésif optique transparent qui améliore le couplage entre les deux et permet la transmission des faisceaux lumineux 210 vers l'extérieur de la vitre d'éclairage 202. Bien sûr, il est possible de prévoir d'autres moyens pour permettre l'extraction des faisceaux lumineux 114a et 114b. En particulier, il est possible de graver des prismes dans la vitre d'éclairage 202. Each patch 402 is fixed on the lighting pane 202 by means of an optical coupling means such as, for example, index liquid or a transparent optical adhesive which improves the coupling between the two and enables the transmission of light beams 210 to the outside of the lighting pane 202. Of course, it is possible to provide other means to allow the extraction of light beams 114a and 114b. In particular, it is possible to engrave prisms in the lighting pane 202.
Le nombre et la répartition des patchs 302, 304 et 402 dépendent de nombreux paramètres, comme par exemple le matériau constituant la vitre d'éclairage 202, la puissance lumineuse délivrée par les sources lumineuses 206a-d, etc.  The number and the distribution of the patches 302, 304 and 402 depend on numerous parameters, such as, for example, the material constituting the lighting pane 202, the light power delivered by the light sources 206a-d, etc.
Selon un mode de réalisation particulier de l'invention, chaque patch 302,304, 402 est un carré de 3 cm de côté, et ils sont espacés d'environ 3 cm les uns des autres.  According to a particular embodiment of the invention, each patch 302, 304, 402 is a square of 3 cm side, and they are spaced about 3 cm apart.
Dans le mode de réalisation de la Fig. 3, la surface des patchs 304 peut représenter entre 30% à 80% de la surface totale de la vitre d'éclairage 202 et de manière préférentielle environ 70%.  In the embodiment of FIG. 3, the surface of the patches 304 may represent between 30% to 80% of the total area of the lighting pane 202 and preferably about 70%.
Les patchs 304 et 402 sont réalisés à partir de films en polyester ou polycarbonate avec des gravures de prismes de 50 ou 200 microns de hauteur et de pas de récurrence du motif.  The patches 304 and 402 are made from polyester or polycarbonate films with prism engravings of 50 or 200 microns in height and no recurrence of the pattern.
L'angle des prismes est choisi selon la direction principale (45°) voulue pour l'extraction des faisceaux lumineux 114a et 114b.  The angle of the prisms is chosen according to the main direction (45 °) desired for the extraction of light beams 114a and 114b.
L'invention évite d'avoir des surépaisseurs sur les vitres d'éclairage 202 du sas 100, les faisceaux lumineux transmis 114a et 114b sont dirigés de manière optimale et facilement adaptable par changement des prismes.  The invention avoids having extra thicknesses on the windows 202 of the airlock 100, the transmitted light beams 114a and 114b are optimally directed and easily adaptable by changing the prisms.
La répartition des patchs permet également d'ajuster l'éclairement au niveau de la zone de capture des images des visages.  The distribution of the patches also makes it possible to adjust the illumination at the area of capture of the images of the faces.
La Fig. 5 montre un mode de répartition particulier de l'invention utilisant des patchs 402 de la Fig. 4.  Fig. 5 shows a particular mode of distribution of the invention using patches 402 of FIG. 4.
La vitre d'éclairage 202 est éclairée le long d'un seul de ses côtés (204a) par une seule source lumineuse 206a. Ici c'est le côté 204a qui est disposé du côté de la sortie 112 c'est-à-dire en amont par rapport au sens d'avancement de l'individu 102.  The lighting pane 202 is illuminated along only one of its sides (204a) by a single light source 206a. Here it is the side 204a which is arranged on the output side 112, that is to say upstream with respect to the direction of advancement of the individual 102.
Le mode de réalisation de la Fig. 5 présente trois zones d'extraction 502a-c, c'est-à-dire au moins deux.  The embodiment of FIG. 5 has three extraction zones 502a-c, i.e. at least two.
Les zones d'extraction 502a-c sont disposées à des distances différentes de la source lumineuse 206a.  The extraction zones 502a-c are arranged at different distances from the light source 206a.
Chaque zone d'extraction 502a-c est constituée d'un ou plusieurs patchs 402 qui sont répartis de manière à obtenir une répartition de l'éclairement pratiquement uniforme le long du passage 108. La première zone d'extraction 502a est la plus proche de la source lumineuse 206a et présente la plus petite surface et elle comprend ici un seul patch 402. Each extraction zone 502a-c consists of one or more patches 402 which are distributed so as to obtain a substantially uniform distribution of illumination along the passageway 108. The first extraction zone 502a is closest to the light source 206a and has the smallest area and here it comprises a single patch 402.
La deuxième zone d'extraction 502b est un peu plus loin de la source lumineuse 206a et elle est constituée ici de trois patchs 402 qui représentent une surface totale supérieure à celle d'un seul patch 402. Comme la deuxième zone d'extraction 502b est plus loin de la source lumineuse 206a que la première zone d'extraction 502a, elle transmet une puissance lumineuse plus faible pour la même surface, c'est pourquoi la mise en place d'une deuxième zone d'extraction 502b ayant une surface plus grande permet de compenser ce manque.  The second extraction zone 502b is a little further from the light source 206a and consists here of three patches 402 which represent a total area greater than that of a single patch 402. As the second extraction zone 502b is farther away from the light source 206a than the first extraction zone 502a, it transmits a lower luminous power for the same surface, which is why setting up a second extraction zone 502b having a larger surface area compensates for this lack.
Le même fonctionnement pour la troisième zone d'extraction 502c implique que la surface totale de la troisième zone d'extraction 502c est supérieure à la surface totale de la deuxième zone d'extraction 502b. Dans le mode de réalisation de l'invention représenté ici, la troisième zone d'extraction 502c présente cinq patchs 402.  The same operation for the third extraction zone 502c implies that the total area of the third extraction zone 502c is greater than the total area of the second extraction zone 502b. In the embodiment of the invention shown here, the third extraction zone 502c has five patches 402.
La surface de chaque zone d'extraction 502a-c est ainsi telle que la puissance lumineuse reçue par le visage de l'individu 102 depuis chaque zone d'extraction 502a- c est sensiblement la même.  The surface of each extraction zone 502a-c is thus such that the light power received by the face of the individual 102 from each extraction zone 502a-c is substantially the same.
Bien sûr, les dimensions et les positions des patchs 402 de chaque zone d'extraction 502a-c et le nombre de zones d'extraction 502a-c peuvent être différents tant que la puissance lumineuse d'éclairement créée par chaque zone d'extraction 502a-c est sensiblement la même pour l'individu passant dans le sas 100.  Of course, the dimensions and positions of the patches 402 of each extraction zone 502a-c and the number of extraction zones 502a-c may be different as long as the illumination light power created by each extraction zone 502a -c is substantially the same for the individual passing through the airlock 100.
Chaque zone d'extraction 502a-c est localisée sensiblement verticalement sur la vitre d'éclairage 202.  Each extraction zone 502a-c is located substantially vertically on the lighting pane 202.
Un dispositif complémentaire de transmission 504 est disposé le long de la tranche qui est opposée à la tranche éclairée par ladite source lumineuse 206a, c'est-à- dire ici le long du côté 204c qui s'étend parallèlement au côté 204a. Le dispositif complémentaire de transmission 504 est destiné à transmettre des faisceaux lumineux 210 qui circulent dans la vitre d'éclairage 202 vers l'extérieur et ainsi apporte un éclairement complémentaire sur le visage de l'individu 102.  A complementary transmission device 504 is disposed along the wafer which is opposite the wafer illuminated by said light source 206a, i.e. here along the side 204c which extends parallel to the side 204a. The complementary transmission device 504 is intended to transmit light beams 210 which circulate in the lighting pane 202 outwards and thus provides additional illumination on the face of the individual 102.
Le dispositif complémentaire de transmission 504 prend par exemple la forme d'un prisme collé sur la tranche de la vitre d'éclairage 202 par l'intermédiaire d'une colle optique.  The additional transmission device 504 takes for example the shape of a prism glued to the edge of the lighting pane 202 by means of an optical glue.
Bien entendu, la présente invention n'est pas limitée aux exemples et modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme de l'art.  Of course, the present invention is not limited to the examples and embodiments described and shown, but it is capable of many variants accessible to those skilled in the art.
