Holopanoragramme                         Machine translation starting from :  

With the difference in a Panorama which is a vast circular table so that a spectator, placed at the center, can look it on 360° to embrace glance all the horizon of a place, Holopanoragramme is of this fact a great semicircular hologram, presenting in foreground in its concavity a real image of an object, so that the spectator, while moving around, can look it on 180°, as if it were directly near the object, sheltered in a recess, to discover all its aspects of them.
While approaching the center of the concavity formed by the holographic support and while leaning through the opening of Holopanoragramme, the observer can also discover a panoramic virtual image located in background.

If one would wish to obtain even more relief by a horizontal angle of vision of 360° degrees around a holographic real image located in front of his support, two would have to be positioned gigantic Holopanoragrammes one opposite the other to close space containing the real image and inside whose the observers should be introduced, which is not easily possible.

By its curve, the support of Holopanoragramme is of this fact directed at the same time towards the left and the right-hand side so that the luminous rays come to laterally prolong the vision of this real image until the optimal angle of one hundred eighty degrees.
The evolution of the relief of the real image is thus carried out without dead angles to the framework of Holopanoragramme, which reinforces the psychological impact, because the observer has the optimal impression thus that the object really exists in space external with the support, whereas it can pass the hand through this immaterial real image.

By the elimination of this last anomaly of the dead angles around a real image, Holopanoragramme reaches the most degree of realism in imagery by offering to us the sharpest feeling of real presence of an object represented remotely, without having to decrease our natural vision by prostheses and without cerebral tiredness, thanks to its real image in four dimensions completely restoring with the high fidelity all the light of the matter of the object while being really formed in space under the eye of the observer.

Thanks to a great angle of vision horizontal and also vertical starting from a large opening, Holopanoragramme entirely restores the totality of the sights around a real image in conformity with the vision of the reality, which can definitively take seat in pedestrian spaces to be visited according to four dimensions, according to its height, its width, its depth and by the exploratory movement of the observers.

A European patent N° 0377724 and one patent of the United States N° 5044708 protect the process from recording on a curved support of this secondary hologram, characterized by the fact that it is not created side dead angles truncating the volume of the image at the time of this reproduction of a primary hologram with great angle of observation.
For the protection of this invention, claim 1 of the European patent N° 0377724 was written in the following way :

1. Method for obtaining an at least partially real an orthoscopic holographic image of an object, including a step a) of construction of a hologram, in which step :

a1) - holographic recording takes place of the image of an object on a first holographic recording material conformed according to a first surface,
a2) - a photographic development of this first holographic recording material is carried out,
a3) - a second holographic recording material conformed according to a second surface which is not parallel to the first surface and exhibits at least one concave part is arranged to face the first holographic recording material which is developed and conformed according to the said first surface, turning the concavity of the said second surface towards the first holographic recording material,
a4) - reconstruction takes place of that pseudoscopic real image of the object which is recorded on the first holographic recording material, at least a part of this reconstructed image being situated in the space bounded by the two holographic recording materials, and holographic recording takes place of this reconstructed image on the second holographic recording material conformed according to the said second surface, and
a5) - a photographic development of the second holographic recording material is carried out,

and a step b) of reconstruction of the at least partially real and orthoscopic holographic image from the hologram constructed, in wich step reconstruction takes place of the holographic image of the object from the second holographic recording material conformed according to the second surface.
