- d’identifier les défauts dans le cristal de façon simple, limitant ainsi le taux de rebut- to identify faults in the crystal in a simple way, thus limiting the scrap rate
- de bien pré-viser le système optique (avec une caméra dite thermique sensible dans la longueur d’onde de référence et mieux dans la plage B), - to pre-aim the optical system (with a so-called thermal camera sensitive in the reference wavelength and better still in range B),

On peut utiliser un seul objectif associé à des capteurs optiques et des détecteurs infrarouge dans la plage A ou un premier objectif associé à des capteurs optiques dans la longueur d’onde de référence et mieux la plage B et un deuxième objectif (en germanium etc) associé à des détecteurs infrarouges dans la plage A. - and even to use a camera or cameras sensitive in the visible spectra (in the range B) and infrared (in the range A), for example based on a division of a beam or by superimposing the detections (in simultaneously capturing infrared and visible images, etc.), to improve the identification and classification of objects in the optical field. It is possible to use a single objective associated with optical sensors and infrared detectors in the A range or a first objective associated with optical sensors in the reference wavelength and better still the B range and a second objective (in germanium, etc.) associated with infrared detectors in range A.
La transmission lumineuse est mesurée pour la longueur d’onde de référence ou mieux pour la plage B avec un spectrophotomètre tel que le Perkin Elmer Lambda-35. Light transmission is measured for the reference wavelength or better for range B with a spectrophotometer such as the Perkin Elmer Lambda-35.
La transmission lumineuse peut être mesurée selon la norme ISO 9050 :2003 en utilisant l’illuminant D65, et être la transmission totale (notamment intégrée dans le domaine du visible et pondérée par la courbe de sensibilité de l’œil humain), tenant compte à la fois de la transmission directe et de l’éventuelle transmission diffuse, la mesure étant faite par exemple à l'aide d'un spectrophotomètre muni d’une sphère intégrante, la mesure à une épaisseur donnée étant ensuite convertie le cas échéant à l’épaisseur de référence de 4mm selon la norme ISO 9050 :2003. The light transmission can be measured according to the ISO 9050: 2003 standard using the illuminant D65, and be the total transmission (in particular integrated in the visible range and weighted by the sensitivity curve of the human eye), taking into account both of the direct transmission and of the possible diffuse transmission, the measurement being made for example using a spectrophotometer equipped with an integrating sphere, the measurement at a given thickness then being converted if necessary to the reference thickness of 4mm according to ISO 9050: 2003.

Et en particulier le matériau de l’insert est choisi parmi: And in particular the material of the insert is chosen from:
- un composé comprenant un sulfure de zinc multispectral, en particulier obtenu après pressage isostatique à chaud (traitement par une presse isostatique sous la température de préférence d’au moins 800°C), notamment incluant du sélénium, tel que ZnSxSei-x avec x de préférence d’au moins 0,97 mieux d’au moins 0,99 et encore mieux d’au moins 0,998 - un composé comprenant un séléniure de zinc, en particulier le ZnSe, notamment incluant du soufre, tel que ZnSeySi-y avec y d’au moins 0,97, mieux d’au moins 0,99 et y encore mieux d’au moins 0,998 un composé comprenant un fluorure de baryum notamment incluant du calcium et/ou du strontium, notamment Bai-i.j CaiSrjF2 avec i+j strictement inférieur à 1 , i et j de préférence chacun d’au plus 0,25 mieux d’au plus 0,03 ou encore mieux d’au plus 0,005 ou encore Bai-iCaiF2avec i strictement inférieur à 1 et de préférence d’au plus 0,25 mieux d’au plus 0,03 ou encore mieux d’au plus 0,005, en particulier le BaF2.- a compound comprising a multispectral zinc sulphide, in particular obtained after hot isostatic pressing (treatment by an isostatic press at a temperature preferably of at least 800 ° C), in particular including selenium, such as ZnS x Sei- x with x preferably at least 0.97 more preferably at least 0.99 and more preferably at least 0.998 - a compound comprising a zinc selenide, in particular ZnSe, in particular including sulfur, such as ZnSe y Si- y with y of at least 0.97, better still of at least 0.99 and even better of y. at least 0.998 a compound comprising a barium fluoride in particular including calcium and / or strontium, in particular Bai-i. j CaiSr j F2 with i + j strictly less than 1, i and j each preferably at most 0.25, better at most 0.03 or even better at most 0.005 or even Bai-iCaiF2 with i strictly less to 1 and preferably at most 0.25, better still at most 0.03 or even better at most 0.005, in particular BaF2.
Le sulfure de zinc avec un grade multispectral (MS) est un matériau récent. Il peut être polycristallin et obtenu en mettant en œuvre (notamment après formation par dépôt chimique en phase vapeur CVD à partir de vapeur de zinc et du gaz H2S) un pressage isostatique à chaud (HIP en anglais). Cela semble supprimer des défauts dans le réseau cristallin, notamment éliminer les cristallites de phase hexagonale en les transformant dans la phase principale cubique, réduire les volumes de pores et homogénéiser la stœchiométrie pour accéder ainsi à la transparence dans le visible. Sa structure est micro(poly)cristalline comportant de grains généralement de 10 à 50pm. Zinc sulfide with multispectral grade (MS) is a recent material. It can be polycrystalline and obtained by implementing (in particular after formation by chemical vapor deposition CVD from zinc vapor and H2S gas) hot isostatic pressing (HIP in English). This seems to remove defects in the crystal lattice, in particular to eliminate the hexagonal phase crystallites by transforming them into the cubic main phase, to reduce the pore volumes and to homogenize the stoichiometry to thereby access transparency in the visible. Its structure is micro (poly) crystalline comprising grains generally of 10 to 50 μm.
Comme indiqué dans l’article “Recrystallization Behavior of Zinc Chalcogenides during Hot Isostatic Pressing” E. M. Gavrishchuk et autres, Inorganics Materials, Vol 50, N°3 2014, le HIP peut être dans une atmosphère d’argon entre 810°C et 1200°C et sous pression de 89 à 200MPa pour une durée de 1 à 22h. As stated in the article “Recrystallization Behavior of Zinc Chalcogenides during Hot Isostatic Pressing” EM Gavrishchuk et al., Inorganics Materials, Vol 50, N ° 3 2014, the HIP can be in an argon atmosphere between 810 ° C and 1200 ° C and under pressure of 89 to 200 MPa for a period of 1 to 22 hours.
La transmission du sulfure de zinc multispectral peut être large spectre avec un spectre plat. La transmission est en particulier supérieure à 60% de 0,5pm à 10pm. Transmission of multispectral zinc sulfide can be broad spectrum with flat spectrum. The transmission is in particular greater than 60% from 0.5 pm to 10 pm.
Le sulfure de zinc multispectral est chimiquement inerte, (quasi) non hygroscopique avec une valeur de solubilité à 20°C de moins de 0,005g dans 100 ml d’eau. Multispectral zinc sulfide is chemically inert, (almost) non-hygroscopic with a solubility value at 20 ° C of less than 0.005g in 100 ml of water.
L’indice de réfraction du ZnS multispectral est par exemple entre 2,1 et 2,3 dans la plage A et dans le visible entre 2,3 et 2,6. The refractive index of multispectral ZnS is, for example, between 2.1 and 2.3 in the range A and in the visible range between 2.3 and 2.6.
Le sulfure de zinc multispectral (notamment polycristallin) est certes généralement moins dur que le sulfure de zinc classique (monospectral) mais cela reste acceptable au vu des avantages optiques précités. Multispectral zinc sulphide (in particular polycrystalline) is admittedly generally less hard than conventional zinc sulphide (monospectral) but this remains acceptable in view of the aforementioned optical advantages.
Le module de rupture de l’insert de sulfure de zinc multispectral peut être supérieur à 60 ou 65MPa. The modulus of rupture of the multispectral zinc sulfide insert can be greater than 60 or 65MPa.
Le sulfure de zinc multispectral est généralement plus résistant que le séléniure de zinc (et moins que le sulfure de zinc classique). Multispectral zinc sulfide is generally stronger than zinc selenide (and less than conventional zinc sulfide).
Le monocristal sulfure de zinc multispectral existe mais est plus difficile à synthétiser (notamment obtenu par la méthode Bridgman de recristallisation sous pression et à température élevée). Un exemple de fabrication du monocristal sulfure de zinc multispectral est donné dans la publication de Gavrishuk et autres J.Crystal Growth 457, 2017, pp. 275-281. The multispectral zinc sulfide single crystal exists but is more difficult to synthesize (in particular obtained by the Bridgman method of recrystallization under pressure and at high temperature). An example of the fabrication of multispectral zinc sulfide single crystal is given in the publication by Gavrishuk et al. J. Crystal Growth 457, 2017, pp. 275-281.
Le sulfure de zinc multispectral et de préférence polycristallin est avantageux en vue sa combinaison de propriétés optiques, mécaniques et résistance chimique. Multispectral and preferably polycrystalline zinc sulfide is advantageous in view of its combination of optical, mechanical and chemical resistance properties.
Le sulfure de zinc multispectral polycristallin le plus connu est le Cleartran™. The best known multispectral polycrystalline zinc sulfide is Cleartran ™.

De préférence, le sulfure de zinc multispectral (ZnSe et plus largement ZnSxSei-x) et de préférence polycristallin présente une pureté (en poids) d’au moins 99,99% ou encore d’au moins 99,995% et mieux encore 99,999% et/ou dénué d’inclusions (et/ou de défauts cristallins) de taille supérieure à 20pm ou même à 12 ou 10pm. Mention may be made of the multispectral ZnS product sold by the company II-VI or Crystaltechno Ltd. Preferably, the multispectral zinc sulphide (ZnSe and more widely ZnS x Sei- x ) and preferably polycrystalline has a purity (by weight) of at least 99.99% or even at least 99.995% and better still 99.999. % and / or free of inclusions (and / or crystal defects) larger than 20 µm or even 12 or 10 µm.
Le séléniure de zinc est moins absorbant que le sulfure de zinc multispectral dans la plage B. Le séléniure de zinc polycristallin peut être également obtenu par CVD à partir de vapeur de zinc et du gaz hhSe. Le monocristal de séléniure de zinc existe mais est plus difficile à synthétiser (notamment obtenu par la méthode Bridgman sous la pression élevée). Zinc selenide is less absorbent than multispectral zinc sulfide in the B range. Polycrystalline zinc selenide can also be obtained by CVD from zinc vapor and hhSe gas. Zinc selenide single crystal exists but is more difficult to synthesize (especially obtained by the Bridgman method under high pressure).
Le séléniure de zinc est chimiquement inerte, (quasi) non hygroscopique notamment avec une valeur de solubilité à 20°C de moins de 0,005g dans 100 ml d’eau. Zinc selenide is chemically inert, (almost) non-hygroscopic, in particular with a solubility value at 20 ° C of less than 0.005 g in 100 ml of water.
La transmission du séléniure de zinc (polycristallin notamment) est large spectre et le spectre est particulièrement plat. La transmission du séléniure de zinc (polycristallin notamment) peut être supérieure à 70% de 0,5pm à 10 pm. The transmission of zinc selenide (polycrystalline in particular) is broad spectrum and the spectrum is particularly flat. The transmission of zinc selenide (polycrystalline in particular) can be greater than 70% from 0.5 μm to 10 μm.
Le module de rupture de l’insert de séléniure de zinc (polycristallin notamment) est supérieur à 50 ou 55 MPa. The modulus of rupture of the zinc selenide insert (especially polycrystalline) is greater than 50 or 55 MPa.
La taille de grains du séléniure de zinc polycristallin peut être entre 50 et 70pm. The grain size of polycrystalline zinc selenide can be between 50 and 70 µm.
On peut citer comme vendeurs de séléniure de zinc polycristallin, les sociétés Hellma, ll-VI ou Crystaltechno Ltd. As sellers of polycrystalline zinc selenide, mention may be made of the companies Hellma, II-VI or Crystaltechno Ltd.
Un exemple de monocristal ZnSeySi-y majoritairement en séléniure de zinc est décrit dans la publication de Kozielski et autres Journal of Crystal growth 30, 1975, ppp 86-92. De préférence, le séléniure de zinc (ZnSeySry et notamment ZnSe) de préférence polycristallin présente une pureté (en poids) d’au moins 99,99% ou encore d’au moins 99,995% et mieux encore 99,999% et/ou dénué d’inclusions (et/ou de défauts cristallins) de taille supérieure à 20pm ou même à 12 ou 10pm. Le fluorure de baryum peut être un monocristal obtenu par exemple par la technique Bridgman - Stockbarger. An example of a ZnSe y Si- y single crystal predominantly made of zinc selenide is described in the publication by Kozielski et al. Journal of Crystal growth 30, 1975, pp 86-92. Preferably, zinc selenide (ZnSe y Sr y and in particular ZnSe) preferably polycrystalline has a purity (by weight) of at least 99.99% or even at least 99.995% and better still 99.999% and / or free of inclusions (and / or crystal defects) larger than 20 µm or even 12 or 10 µm. The barium fluoride can be a single crystal obtained, for example, by the Bridgman-Stockbarger technique.
Avantageusement, le fluorure de baryum peut être polycristallin (céramique) et obtenu avec la méthode de synthèse à partir de monocristaux de fluorure de baryum ce qui permet d’augmenter la tenue mécanique (limiter la fissuration de monocristaux à cause de clivage. Un exemple de fabrication du fluorure de baryum céramique est donné dans la publication de Fedorov et autres Inorganic Materials 50, 2014, pp. 738-744. Advantageously, the barium fluoride can be polycrystalline (ceramic) and obtained with the synthesis method from single crystals of barium fluoride which makes it possible to increase the mechanical strength (limit the cracking of single crystals due to cleavage. An example of fabrication of ceramic barium fluoride is given in the publication by Fedorov et al. Inorganic Materials 50, 2014, pp. 738-744.
Le fluorure de baryum est faiblement hygroscopique, notamment avec une valeur de solubilité à 20°C de moins de 0,2g dans 100 ml d’eau. On le préfère avec un diamètre équivalent d’au plus 1cm par précaution. Le module de rupture de l’insert de fluorure de baryum peut être supérieur à 25MPa. Barium fluoride is weakly hygroscopic, in particular with a solubility value at 20 ° C of less than 0.2 g in 100 ml of water. It is preferred with an equivalent diameter of at most 1cm as a precaution. The modulus of rupture of the barium fluoride insert can be greater than 25MPa.
La transmission du fluorure de baryum peut être large spectre, avec un spectre plat. La transmission du fluorure de baryum peut être supérieure à 80% de 0,5pm à 10pm. Comme monocristal de fluorure de baryum on peut citer le produit vendu par la société Hellma ou Crystaltechno Ltd. The transmission of barium fluoride can be broad spectrum, with a flat spectrum. The transmission of barium fluoride can be greater than 80% from 0.5pm to 10pm. As barium fluoride single crystal, mention may be made of the product sold by the company Hellma or Crystaltechno Ltd.
De préférence, le fluorure de baryum (Bai-i.j CaiSrjF2 ou encore BaCa,F2 et notamment BaF2) de préférence polycristallin présente une pureté (en poids) d’au moins 99,99% ou encore d’au moins 99,995% et mieux encore 99,999% et/ou dénué d’inclusions (et/ou de défauts cristallins) de taille supérieure à 20pm ou même à 12 ou 10pm. Preferably, the barium fluoride (Bai-i. J CaiSr j F2 or even BaCa, F2 and in particular BaF2) preferably polycrystalline has a purity (by weight) of at least 99.99% or even of at least 99.995 % and better still 99.999% and / or free of inclusions (and / or crystal defects) larger than 20 µm or even 12 or 10 µm.
De préférence, pour davantage de stabilité, comme décrit dans la publication de Duvel et autres Solid State Sciences 83, 2018, pp 188-191 i et j sont faibles en particulier i est d’au plus 0,03, et j d’au plus 0,03 et même mieux encore i d’au plus 0,005, j d’au plus 0,005. Preferably, for more stability, as described in the publication of Duvel et al. Solid State Sciences 83, 2018, pp 188-191 i and j are weak in particular i is at most 0.03, and j at plus 0.03 and even better still i at most 0.005, j at most 0.005.
Avantageusement pour améliorer la résistance mécanique, l’insert comprenant une face extérieure et une face intérieure, il comporte une couche de protection mécanique et/ou chimique sur la face extérieure et éventuellement sur la face intérieure. Advantageously to improve the mechanical resistance, the insert comprising an outer face and an inner face, it comprises a mechanical and / or chemical protection layer on the outer face and possibly on the inner face.
La couche de protection mécanique et/ou chimique (de préférence un revêtement - monocouche ou multicouche -) peut être choisie parmi au moins l’une des couches suivantes: The mechanical and / or chemical protective layer (preferably a coating - monolayer or multilayer -) can be chosen from at least one of the following layers:
- une couche comprenant un sulfure de zinc (notamment ZnS) en particulier sur un insert de ZnSxSei-x, notamment ZnSe, pour une protection mécanique, - a layer comprising a zinc sulphide (in particular ZnS) in particular on an insert of ZnS x Sei- x , in particular ZnSe, for mechanical protection,
- une couche diamant, de préférence amorphe pour ses propriétés d’adhésion au cristal de l’insert, notamment d’épaisseur d’au moins 10nm ou 20nm et de préférence de 50nm à 300nm et même d’au plus 100nm, - une couche DLC (pour « diamond like carbon » en anglais), c’est à dire une couche à base de carbone de type diamant, de préférence amorphe, notamment d’épaisseur d’au moins 10nm ou 20nm et de préférence de 50nm à 300nm et même d’au plus 100nm. a diamond layer, preferably amorphous for its properties of adhesion to the crystal of the insert, in particular with a thickness of at least 10 nm or 20 nm and preferably from 50 nm to 300 nm and even at most 100 nm, a DLC layer (for “diamond like carbon” in English), that is to say a layer based on carbon of the diamond type, preferably amorphous, in particular with a thickness of at least 10 nm or 20 nm and preferably 50 nm at 300nm and even at most 100nm.
L’ajout d’une couche suffisamment mince de ZnS sur ZnSe ne dégrade pas la transmission et garantit une résistance à l’érosion similaire au ZnS massif. Un exemple de produit est le TUFTRAN™ de la société Rohm & Haas. Adding a sufficiently thin layer of ZnS over ZnSe does not degrade transmission and ensures erosion resistance similar to massive ZnS. An example of a product is TUFTRAN ™ from Rohm & Haas.
Par exemple le matériau tel que le ZnSxSei-x (dont ZnS) peut être revêtu par une couche de ZnS pour le protéger contre des acides et autres solvants spécifiques comme le méthanol etc. For example the material such as ZnS x Sei- x (including ZnS) can be coated with a layer of ZnS to protect it against acids and other specific solvents such as methanol etc.
Alternativement au ZnS, on peut donc déposer par exemple par dépôt en phase chimique (notamment PECVD) ou dépôt en phase vapeur (PVD) une couche diamant (ou une couche DLC) sans dégrader la transmission et en garantissant une résistance à l’érosion encore plus grande. Un exemple de fabrication est décrit dans la publication de Osipkov et autres IOP conf. Ser. Material Science and Engineering 74 (2015) 012013. As an alternative to ZnS, it is therefore possible to deposit, for example by chemical phase deposition (in particular PECVD) or vapor phase deposition (PVD), a diamond layer (or a DLC layer) without degrading the transmission and ensuring further erosion resistance. bigger. An example of manufacture is described in the publication of Osipkov et al. IOP conf. Ser. Material Science and Engineering 74 (2015) 012013.

Le verre intérieur et/ou extérieur peut être neutre (sans coloration), ou (légèrement) teinté notamment gris ou vert, tel le verre TSA de la société Saint-Gobain Glass. Le verre intérieur et/ou extérieur peut avoir subi un traitement chimique ou thermique du type durcissement, recuit ou une trempe (pour une meilleure résistance mécanique notamment) ou être semi trempé. - a second glazing, in mineral glass, preferably curved and preferably clear or extra-clear or even tinted, forming interior glazing, with third and fourth main faces, if a motor vehicle preferably has a thickness less than that of the first glazing, even d 'at most 2mm - in particular 1, 9mm, 1, 8mm, 1.6mm and 1, 4mm - or even at most 1, 3mm or at most 1mm, the thickness of the first and second glazing preferably being strictly less than 4mm, even at 3.7mm. The interior and / or exterior glass can be neutral (without coloring), or (slightly) tinted, in particular gray or green, such as TSA glass from Saint-Gobain Glass. The interior and / or exterior glass may have undergone a chemical or thermal treatment of the hardening, annealing or tempering type (for better mechanical resistance in particular) or be semi-tempered.
Sans sortir du cadre de l’invention, l’intercalaire peut bien entendu comprendre plusieurs feuillets en matière thermoplastique de natures différentes, par exemple de duretés différentes pour assurer une fonction acoustique, comme par exemple décrit dans la publication US 6,132,882, notamment une ensemble de feuillets de PVB de duretés différentes. De même l’une des feuilles de verres peut être amincie par rapport aux épaisseurs classiquement utilisées. Without departing from the scope of the invention, the interlayer may of course comprise several sheets of thermoplastic material of different natures, for example of different hardnesses to ensure an acoustic function, as for example described in the publication US Pat. No. 6,132,882, in particular a set of PVB sheets of different hardnesses. Likewise, one of the glass sheets can be thinned compared to the thicknesses conventionally used.
L’intercalaire peut selon l’invention présenter une forme en coin, notamment en vue d’une application HUD (Head Up Display pour visualisation tête haute). Egalement l’un des feuillets de l’intercalaire peut être teinté dans la masse. According to the invention, the spacer may have a wedge shape, in particular with a view to a HUD (Head Up Display) application. Also one of the leaflets of the interlayer can be colored in the mass.
Comme intercalaire de feuilletage usuel, outre le PVB, on peut citer le polyuréthane PU utilisé souple, un thermoplastique sans plastifiant tel que le copolymère éthylène/acétate de vinyle (EVA), une résine ionomère. Ces plastiques ont par exemple une épaisseur entre 0,2 mm et 1,1mm, notamment 0,3 et 0,7mm. As usual lamination interlayer, in addition to PVB, mention may be made of the flexible polyurethane PU used, a plasticizer-free thermoplastic such as ethylene / vinyl acetate (EVA) copolymer, an ionomer resin. These plastics have, for example, a thickness between 0.2 mm and 1.1 mm, in particular 0.3 and 0.7 mm.
L’intercalaire de feuilletage peut comprendre un autre film plastique fonctionnel (transparent, clair ou teinté) par exemple un film en poly(éthylène téréphtalate) PET porteur d’une couche athermique, électroconductrice etc par exemple on a PVB/ film fonctionnel/PVB entre les faces F2 et F3. The lamination interlayer can comprise another functional plastic film (transparent, clear or tinted), for example a poly (ethylene terephthalate) PET film carrying an athermic, electrically conductive layer, etc., for example, we have PVB / functional film / PVB between the faces F2 and F3.
Le film plastique transparent peut être d'une épaisseur comprise entre 10 et 100 pm. Le film plastique transparent peut être plus largement en polyamide, polyester, polyolefine (PE : polyéthylène, PP : polypropylène), polystyrène, polyvinyle chloride (PVC), poly téréphtalate d’éthylène (PET), polyméthacrylate de méthyle (PMMA), polycarbonate (PC). On préfère un film clair notamment le PET. The transparent plastic film can be between 10 and 100 µm thick. The transparent plastic film can be more widely polyamide, polyester, polyolefin (PE: polyethylene, PP: polypropylene), polystyrene, polyvinyl chloride (PVC), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polycarbonate (PC). A clear film, in particular PET, is preferred.
Comme on peut utiliser par exemple un film clair de PET revêtu, par exemple XI R de la société Eastman, un film coextrudé en PET-PMMA, par exemple du type SRF 3M®, mais aussi de nombreux autres films (par exemple en PC, PE, PEN, PMMA, PVC), qui sont visuellement aussi transparents que possible et ne se modifient pas dans l'autoclave en ce qui concerne leur surface et leur consistance. As one can use for example a clear film of coated PET, for example XI R from the company Eastman, a coextruded film of PET-PMMA, for example of the SRF 3M® type, but also many other films (for example of PC, PE, PEN, PMMA, PVC), which are visually as transparent as possible and do not change in the autoclave with regard to their surface and consistency.
Afin de limiter réchauffement dans l’habitacle ou de limiter l’usage d’air conditionné, l’une des feuilles de verre au moins (de préférence le verre extérieur) est teintée, et le vitrage feuilleté peut comporter également une couche réfléchissant ou absorbant le rayonnement solaire, de préférence en face F4 ou en face F2 ou F3, en particulier une couche d’oxyde transparent électro-conducteur dite couche TCO (en face F4) ou même un empilement de couches minces comprenant au moins une couche TCO, ou d’empilements de couches minces comprenant au moins une couche d’argent (en F2 ou F3), la ou chaque couche d’argent étant disposée entre des couches diélectriques.In order to limit heating in the passenger compartment or to limit the use of air conditioning, at least one of the glass sheets (preferably the exterior glass) is tinted, and the laminated glazing may also include a reflective or absorbent layer. solar radiation, preferably on the face F4 or on the face F2 or F3, in particular an electro-conductive transparent oxide layer called the TCO layer (on the face F4) or even a stack of thin layers comprising at least one TCO layer, or stacks of thin layers comprising at least one silver layer (in F2 or F3), the or each silver layer being disposed between dielectric layers.
On peut cumuler couche (à l’argent) en face F2 et/ou F3 et couche TCO en face F4.We can combine a layer (silver) on face F2 and / or F3 and a TCO layer on face F4.
La couche TCO (d’un oxyde transparent électro-conducteur) est de préférence une couche d’oxyde d’étain dopé au fluor (SnC>2:F) ou une couche d’oxyde mixte d’étain et d’indium (ITO). The TCO layer (of an electrically conductive transparent oxide) is preferably a layer of tin oxide doped with fluorine (SnC> 2: F) or a layer of mixed tin and indium oxide (ITO ).
Naturellement l’application la plus recherchée est que le vitrage soit un pare-brise d’un véhicule routier (automobile) ou même ferroviaire (à vitesse modérée). Of course, the most popular application is for the glazing to be a windshield of a road vehicle (automobile) or even a rail vehicle (at moderate speed).
Le vitrage selon l’invention peut comporter au moins une première feuille de verre comportant sur une face principale une couche opaque (de masquage) notamment un émail (noir etc) en bordure du trou traversant (de façon à masquer la ou les caméras par exemple).

La figure 1 schématise un pare-brise 100 selon l’invention, en coupe avec une caméra thermique 7 placée derrière le pare-brise face à une zone qui se situe de préférence dans la partie centrale et supérieure du pare-brise. Dans cette zone, la caméra est orientée avec un certain angle vis-à-vis de la surface du pare-brise (face F4). En particulier, l’objectif et les capteurs infrarouge sont orientés directement vers la zone de saisie d’images, selon une direction proche de la parallèle au sol, c'est-à-dire seulement légèrement inclinée vers la route. Autrement dit, la caméra 7 est orientée vers la route selon un angle faible avec un champ 70 adapté pour remplir ses fonctions. Figure 1 schematically shows a windshield 100 according to the invention, in section with a thermal camera 7 placed behind the windshield facing an area which is preferably located in the central and upper part of the windshield. In this area, the camera is oriented at a certain angle with respect to the surface of the windshield (face F4). In particular, the lens and the infrared sensors are oriented directly towards the image capture area, in a direction close to parallel to the ground, that is to say only slightly inclined towards the road. In other words, the camera 7 is oriented towards the road at a low angle with a field 70 adapted to fulfill its functions.
Le pare-brise est un vitrage feuilleté classique comprenant : The windshield is a classic laminated glazing comprising:

De façon classique et bien connue, le pare-brise est obtenu par feuilletage à chaud des éléments 1 , 2 et 3. Conventionally and well known, the windshield is obtained by hot lamination of the elements 1, 2 and 3.
Le pare-brise 100 comporte sur la face extérieure 11 par exemple (ou de préférence en F2 et/ou en face F3 ou F4) de préférence un revêtement opaque par exemple noir 6, tel qu’une couche d’émail ou de laque noire, sur toute la surface du vitrage disposée en regard du dispositif incorporant la caméra thermique (sur tout le pourtour du trou donc), y compris son boîtier 8 (plastique, métal etc), de manière à cacher celui-ci. Le boîtier 8 peut être collé à la face F4 par une colle 80 et au toit 9. The windshield 100 comprises on the outer face 11 for example (or preferably in F2 and / or on the face F3 or F4) preferably an opaque coating, for example black 6, such as a layer of enamel or black lacquer. , over the entire surface of the glazing arranged opposite the device incorporating the thermal camera (therefore over the entire periphery of the hole), including its housing 8 (plastic, metal, etc.), so as to hide it. The box 8 can be glued to the face F4 by an adhesive 80 and to the roof 9.
La couche opaque 6 peut s’étendre au-delà de la zone avec l’insert. Eventuellement l’extension (latérale) de la couche opaque formant une bande en bordure supérieure du trou traversant pour que le pare-brise ait une bande opaque (noire) le long du bord longitudinal supérieur voire même un cadre opaque (noir) sur toute la périphérie.
