Description
Procédé et dispositif d'exploration d'oeuvres d'art et, en particulier, des peintures de Léonard de Vinci. Process and device for exploring works of art and, in particular, paintings by Leonardo da Vinci.
La présente invention concerne l'exploration d'oeuvres d'art et, en particulier, des peintures de Léonard de Vinci et est relative à un dispositif permettant de mettre en évidence des écrits ou dessins non observables à l'oeil nu, de même que des dimensions picturales différentes. The present invention relates to the exploration of works of art and, in particular, to paintings by Leonardo da Vinci and relates to a device making it possible to highlight writings or drawings not observable with the naked eye, as well as different pictorial dimensions.
Les techniques d'analyse actuelles ne permettent pas d'obtenir des caractéristiques suffisantes sur Les oeuvres d'art et, en particulier, les peintures ce Léonard de Vinci. C'est pourquoi jusqu'à ce jour i t est difficile de les authentifier. Ces peintures étant conçues avec des pigmentations naturelles, aucun moyen de radiographie ne permet de révéler des détails importants sur leur conception et ne permet pas non plus de voir la griffe du Maître, Léonard de Vinci. Current analysis techniques do not allow obtaining sufficient characteristics on works of art and, in particular, paintings by Leonardo da Vinci. This is why to date i t is difficult to authenticate them. These paintings being designed with natural pigments, no means of radiography can reveal important details on their design and does not allow to see the label of the Master, Leonardo da Vinci.
On connaît l'art de l'anamorphose, c'est-à-dire la projection distordue d'un dessin ou d'une Deinture, qui est vue dans la forme vrai quand elle est vue à une certaine distance, selon un certain angle et à travers un miroir. Cette technique a été utilisée pour étudier des tableaux de peintres céleores, tels que Durer, Holbein, Léonard de Vinci.
On connaît également le procédé d'image informatique, tel que décrit dans Optical Engineering, vol.28 n°7, juillet 89, page 800 à 804, qui a servi à comparer les "Hona Lisa" du Louvre et de Isleworth. We know the art of anamorphosis, that is to say the distorted projection of a drawing or a Dye, which is seen in true form when it is seen at a certain distance, at a certain angle and through a mirror. This technique was used to study paintings by famous painters, such as Durer, Holbein, Leonardo da Vinci. We also know the computer image process, as described in Optical Engineering, vol.28 n ° 7, July 89, pages 800 to 804, which served to compare the "Hona Lisa" of the Louvre and Isleworth.
Les analyses d'exploration informatique réalisées ont permis de suggérer une origine commune pour les deux tableaux à partir de deux sujets ou modèles différents. The computer exploration analyzes carried out made it possible to suggest a common origin for the two tables from two different subjects or models.
Ces deux méthodes connues, l'anamorphose et le procédé informatique, ne permettent cependant pas αe faire apparaître ce qui se trouve sur le tableau : des ocjets, des écrits, de personnages apparaissent, des choses évoluent, l'image est en mouvement. These two known methods, anamorphosis and the computer process, however, do not allow us to reveal what is on the board: objects, writings, characters appear, things evolve, the image is in movement.
La présente invention a pour but de mettre en évidence ces étonnantes caractéristiques des peintures de Léonard de Vinci et, par extension, celles d'autres Maîtres. Le procédé suivant l'invention consiste à éclairer le tableau à explorer d'une puissante lumière sous un angle d'incidence approprié, via un miroir de renvoi et à visualiser les phénomènes, qui se présentent dans la lumière réfléchie par le tableau sous un angle déterminé par l'adaptateur. The purpose of the present invention is to highlight these astonishing characteristics of the paintings of Leonardo da Vinci and, by extension, those of other Masters. The method according to the invention consists in illuminating the table to be explored with powerful light at an appropriate angle of incidence, via a deflecting mirror and in visualizing the phenomena which occur in the light reflected by the table from an angle. determined by the adapter.
Pour réaliser le procédé est prévu suivant l'invention un dispositif caractérisé en ce qu'il comporte un spot halogène, envoyant une lumière faiblement divergente, un miroir, recevant ce faisceau lumineux et le réfléchissant vers le tableau à explorer ou une reproduction photographique de qualité de ce tableau sous un angle, de manière à visualiser les Dnénomènes apparaissant en détectant les faisceaux réfléchis et diffusés sous un angle approprié.
L'invention est exposée ci-après plus en détail sur la base des dessins annexés, à titre d'exemple uniquement, montrant en : Figure 1 une vue schématique du dispositif d'exploration suivant l'invention. To carry out the process, a device is provided according to the invention, characterized in that it comprises a halogen spot, sending a slightly diverging light, a mirror, receiving this light beam and reflecting it towards the picture to be explored or a high-quality photographic reproduction. of this table at an angle, so as to visualize the phenomena appearing by detecting the reflected and scattered beams at an appropriate angle. The invention is set out below in more detail on the basis of the appended drawings, by way of example only, showing in: Figure 1 a schematic view of the exploration device according to the invention.
Figures 2 et 3 deux images obtenues suivant l'invention montrant certains des phénomènes apparus. Figures 2 and 3 two images obtained according to the invention showing some of the phenomena appeared.
Suivant le dispositif expérimental, représenté en figure 1, un spot halogène 1 envoit vers un miroir 2 une lumière blanche faiblement divergente. Pour faire ressortir certains phénomènes, on utilisera avantageusement des lumières de couleurs. According to the experimental device, represented in FIG. 1, a halogen spot 1 sends a slightly diverging white light towards a mirror 2. To bring out certain phenomena, we will advantageously use colored lights.
Le miroir 2 réfléchit le faisceau lumineux vers une peinture 3, qui peut être une reproduction photographique de bonne qualité, sous un angle d'incidence i. The mirror 2 reflects the light beam towards a painting 3, which can be a good quality photographic reproduction, at an angle of incidence i.
Une caméra vidéo 4 détecte les faisceaux réfléchis ou diffusés sous un angle r. A video camera 4 detects the reflected or scattered beams at an angle r.
Un appareil de télévision 5 permet de visualiser les phénomènes, qui se présentent. A television apparatus 5 makes it possible to visualize the phenomena which arise.
Les angles i et r sont adaptés de façon à rendre compte le mieux possible de ces phénomènes. Ceux-ci peuvent être visualisés l'oeil nu, si celui-ci est mis en lieu et place de la caméra mais l'avantage de l'utilisation de cette dernière est d'enregistrer l'image obtenue The angles i and r are adapted so as to give the best possible account of these phenomena. These can be viewed with the naked eye, if it is in place of the camera but the advantage of using the latter is to record the image obtained.
La toile originale n'est pas nécessaire pour utiliser le procédé suivant l'invention. L'exploration de bonnes reproductions photographiques suffit.
Les résultats expérimentaux de l'exploration de deux tableaux de Léonard de Vinci : la Joconde et un autoportrait, ont mis en évidence un certain nombre de phénomènes différents : The original canvas is not necessary to use the process according to the invention. Exploring good photographic reproductions is enough. Experimental results from the exploration of two Leonardo da Vinci paintings: the Mona Lisa and a self-portrait, have highlighted a number of different phenomena:
1. le personnage central change d'aspect, des objets, des écrits, des formules mathématiques, des personnages apparaissent ; 2. certaines des choses apparues évoluent lentement, l'image est en mouvement ; 1. the central character changes appearance, objects, writings, mathematical formulas, characters appear; 2. some of the things that appear slowly evolve, the image is in motion;
3. en agrandissant certains détails miniaturisés (1 cm) du tableau une nouvelle image apparaît avec une très bonne définition. 3. by enlarging certain miniaturized details (1 cm) of the table a new image appears with very good definition.
Dans le tableau de la Joconde comme dans l'auto-portrait on peut ainsi remarquer une série d'éléments : In the Mona Lisa painting as in the self-portrait, we can thus notice a series of elements:
en 6 - personnage de grande dimension, in 6 - large character,
en 7 - écritures, in 7 - writings,
en 8 - personnages de petite dimension, in 8 - small characters,
en 9 - personnages de di mensions intermédiaires, in 9 - characters of intermediate dimensions,
en 10 - bâtiments, in 10 - buildings,
en 11 - chiffres, in 11 - numbers,
en 12 - dimension optique, in 12 - optical dimension,
en 13 - kaléidoscope, in 13 - kaleidoscope,
en 14 - technique invisible. in 14 - invisible technique.
Le procédé suivant l'invention appliqué à un tableau de Léonard de Vinci démontre des techniques picturales inconnues à ce jour du monde des arts. Léonard de Vinci a assimilé dans son oeuvre différentes dimensions picturales, mathématiques, scientifiques et optiques. Une dimension picturale invisible à l'oeil apparaît spontanément avec le procédé suivant l'invention.
Grâce à l'invention on obtient des avantages essentiels par rapport aux techniques d'analyses utilisées à ce jour ; le procédé, simple et peu coûteux, apporte de surprenants renseignements sur la technique picturale de Léonard de Vinci.
