Abstract

A spherical case (1) of hard plastics material has a slot in the top for a shutter plane film and its cover. Light enters through a large opening without a diaphragm but with a sun shade (3) which acts as a zoom element. This element slides in a ring (7) located in the end of a tube (6) which houses a lens assembly containing a spherical mirror (8) behind which is a concave correction lens (9). A gyratory shutter (11) operating on side axes has positioning magnets with attraction and arresting forces. An observation window (4) with a telescopic tube (5) includes a magnifying lens enabling adjustments to be made for wide angle or close up photography. The whole assembly is mounted on a member (12) which allows lengthways positioning movements to be made.

Description

L'invention se rapporte à un montage optique à r flexions, s'inscrivant dans les les domaines techniqpes de la photographie et du relief. The invention relates to an optical assembly with r flexions, falling within the technical fields of photography and relief.

A titre d'exemple simple, le stéréoscope ou instrument d'optique dans lequel deux images planes superposées par la visioii binoculaire donnent l'impression d'une seule image en relief, nécessite une utilisation individuelle. As a simple example, the stereoscope or optical instrument in which two plane images superimposed by the binocular view give the impression of a single image in relief, requires individual use.

Quant à l'additif selon l'invention, il permet d'abord de prendre de la distance par rapport au sujet visé ct à pIotogra- phier. De la réduction du volume ressort la possibilité visuelle de couvrir un angle de champ important, avec formation d'une lma- ge binoculaire sur une surface sphérique intermédiaire corrigée.  As for the additive according to the invention, it first makes it possible to take distance from the subject in question and to photograph. The reduction in volume brings out the visual possibility of covering a large angle of field, with the formation of a binocular lamination on a corrected intermediate spherical surface.

Elle est reproduite directement suivant l'emploi, indirectement suivant la méthode traditionnelle et le procédé de prise de vue en plein centre du système. Il résulte une synthèse photogénique ayant pour effet d'obtenir le relief assorti d'une grande profondeur de champ. It is reproduced directly according to use, indirectly according to the traditional method and the method of shooting in the center of the system. This results in a photogenic synthesis having the effect of obtaining the relief accompanied by a large depth of field.

Pour se faire, le dispositif aux données non limitatives suivantes, comprend trois éléments principaux
Le cheminement des rayons lumineux successivement inversé, renversé, passe au travers d'une loupe de netteté et de première correction 3 plan convexe, aux valeurs indicatives de TO millimètres et 19,50 dioptries, s'actionne avec son support mobile, coulissante, maintenue dans une bague 7 ; ainsi réglable suivant l'axe optique, peut avoir une course de 9 millimètres, venant prendre appui sur la spiricité, puis selon, faire varier la distance focale a-fin d'être utilisé comme, un zoom, et ce,à laide du pare-soleil rigide, protecteur.
To do this, the device with the following non-limiting data includes three main elements
The path of the light rays successively inverted, inverted, passes through a magnifying glass of sharpness and first correction 3 convex plane, at indicative values of TO millimeters and 19.50 diopters, is operated with its mobile, sliding, maintained support in a ring 7; thus adjustable along the optical axis, can have a stroke of 9 millimeters, coming to bear on the spiricity, then according to, varying the focal distance a-end of being used as, a zoom, and this, using the lens - rigid, protective sun.

Après réfraction, l'image est réfléchie sur une sphère en cristal 8 de substance très limpide, environ distante de 1 à 9 millimètres du plan de la lentille précédente. Le miroir y ex- celle, son diamètre de 89 millimètres, équivalent ou voisin de la distance séparant les centres optiques des yeux et leurs rayons, en fait pour l'observateur, un capteur monoculaire centré, donnant une vue globale ou perspective de grand champ. After refraction, the image is reflected on a crystal sphere 8 of very clear substance, approximately 1 to 9 millimeters distant from the plane of the previous lens. The mirror there ex- that, its diameter of 89 millimeters, equivalent or close to the distance separating the optical centers of the eyes and their rays, in fact for the observer, a centered monocular sensor, giving a global view or perspective of large field .

Les points lumineux situés a l'infini, réduisent le volume et reproduisent lai fusion des deux images autrement et naturelle- ment perçue en relief. The luminous points located at infinity, reduce the volume and reproduce the fusion of the two images differently and naturally perceived in relief.

Le flux lumineux est dc nouveau réfracté, réfléchi et corrigé des aberrations, une lentille plan concave 9 reflet finalement une image perspective nette, circulaire mais réelle à trois dimensions. The luminous flux is once again refracted, reflected and corrected for aberrations, a concave plane lens 9 finally reflects a sharp, circular but real three-dimensional perspective image.

Le foyer relais peut être projet sur un plan film annexe, mais encore et surtout être photographié ou filmé avec maints appareils à objectifs commercialisés. The focal point can be projected on an additional film plan, but also and above all be photographed or filmed with many commercial cameras.

Le groupe de lentilles disposé dans un tube de blocage en matière plastique 6, détermine un objectif à focale variable de 130 à 140 millimètres environ. L'ensemble est ajusté, inséré dans un bottier 1 dont la forme symbolise l'espace courbe. La coque dure plastique, chargée de polystirène e son étage supérieur, a une zone délimitée et consolidée au niveau de la fente du volet ou chSssis plan film avec son catche 2 facultatif, constitué sur les côtés et en son étage inférieur de matière plus rigide. The group of lenses arranged in a plastic blocking tube 6, determines a variable focal length lens from 130 to 140 millimeters approximately. The whole is adjusted, inserted in a shoemaker 1 whose shape symbolizes the curved space. The hard plastic shell, loaded with polystyrene e its upper stage, has a delimited and consolidated zone at the level of the slot of the shutter or film frame chassis with its optional catche 2, formed on the sides and in its lower stage of more rigid material.

L'entrée de la lumière se fait à grande ouverture, le faisceau non diaphra6me, seul le pare-soleil de révolution et de mise au point pouvant être équipé de l'accessoire filtre à visser, règle suivant l'axe horizontal le grand-angulaire. Un store opturateur giratoire 11 facultatif, muni de sa lunette centrale, orifico d'un diamètre approximatif de 60 millimètres, avec ses aimants de positionnements de forces attirantes et d'arrêt de forces contraires, peut basculer sur des axes latéraux solidement fichées, complète le dispositif en le rendant autonome. The light is entered at a wide aperture, the beam not diaphra6me, only the sunshade of revolution and focusing can be equipped with the screw-on filter accessory, adjusts along the horizontal axis the wide angle . An optional revolving awning 11, fitted with its central bezel, orifico with an approximate diameter of 60 millimeters, with its magnets for positioning attractive forces and stopping opposing forces, can tilt on firmly attached lateral axes, completes the device by making it autonomous.

A la sortie nous trouvons 4 une fenêtre de visée, d'un dianè- tre relatif mesuré à 8 centimètres, et postérieurement une loupe à visser facultative, permettant de grossir l'image et d1effec- tuer des mises au point nécessaires pour la photographie rappro chée ou de grand-angle. Sa: correction dioptrique est réglable, cette loupe soit indépendante ou montée sur le conduit télesco- pique présente en coupe 5, est extraite éventuellement après avoir obtenu le champ complet recherché. At the exit we find 4 an aiming window, of a relative diameter measured at 8 centimeters, and subsequently an optional screw-on magnifying glass, allowing to magnify the image and to carry out the necessary adjustments for close-up photography wide or wide angle. Sa: dioptric correction is adjustable, this magnifier is independent or mounted on the telescopic duct present in section 5, is possibly extracted after obtaining the desired full field.

L'additif amovible peut être support par une traverse en duralumin 12, de section rectangulaire, rainurée tout en epais- seur, évidée sur une longueur utile a la translation de l'appareil photographique, en fonction dc l'objectif en regard. Le dispositif verrouillé 13, fixé 10, rendu solidaire, peut attPin- dre 75 centimètres hors tout, et h volonte, titre installé sur trépied.  The removable additive can be supported by a duralumin cross member 12, of rectangular section, grooved while thick, hollowed out over a length useful for the translation of the camera, depending on the facing lens.
