Holopanoragramme with space-time high definition

Thanks to the total and extremely condensed writing holography, only one support holographic can diffuse at the same time many sights different on the relief from a fixed object, until being able to restore through its opening the integrality of its relief.
This new faculty requires an appreciation of the volume of the image according to the fourth dimension, time, at the time of the exploratory movement of the observer of which the duration depends on the number from different points of view inside the horizontal and vertical angles of vision.
With the difference of the traditional graphic definition of a plane image in a number of points, a holographic image is appreciated of this fact starting from its space-time definition in a number from points of view.

In the old stereoscopic process in photography or cinematography, an exploratory movement of the observer does not enable him to discover new aspects of the relief, being given the limited number of visual information only brought starting from two points of view according to only one horizontal line.
As soon as the observer slightly rocks its head by positioning its eyes according to an oblique line compared to the horizontal line on which the stereoscopic couples of images starting from the two only points of view on the object were taken, its brain is unable to correct the error of parallelism to amalgamate the two images.
The depth perception is then impossible and the vision becomes unpleasant and tiring.
Thus, any system not bringing any new information on the relief at the time of an exploratory movement following the vertical, requires a perfectly right position of the head of the observer, or more exactly than the line passing by its eyes is perfectly parallel to the horizontal line passing by the two points of view of the stereoscopic images.
By a translation on a horizontal level of observation of this horizontal line passing by its eyes, the brain of the observer always manages to amalgamate these two images.
But as of the least displacement of its body, it feels a light imbalance then, because its cerebral image of the simulated relief moves abnormally at the same time as him without it being able to see evolving the relief in accordance with reality, since this one remains visible only under the same points of view.
This incoherent displacement of the cerebral image of the relief simulated at the time of an exploratory movement of the observer, returns to a situation in which an object with three dimensions would follow perfectly the displacement of an observer, to remain always visible under the same points of view with the same prospect.

This new disadvantage of the stop of the apparent evolution of the relief is of course present in a hologram of an old stereoscope representing completely only one stereoscopic couple of images at two dimensions.

This use of holography in stereoscopy is used to separately direct the right image and the left image towards the eye corresponding while eliminating from separating optics like a lenticular system or filter glasses, thanks to the property of a hologram to diffract the luminous rays in quite precise directions.
Only, the visual imperfections of the simulated relief are found obviously in a holographic image completely representing the plane images of this old stereoscopy, instead of directly representing the object in volume with the totality of its information.
A succession of images to two dimensions taken around an object with three dimensions can then be holographed in this holographic stereogram in order to present new points of view at the time of an exploratory movement of the observer.
But an insufficient number from points of view results in an evolution jerked of the relief, and more particularly in-depth.

A jerked evolution of the relief is similar to the gradual evolution of the needle of the seconds of a watch whose jump between each stop becomes broader at the ends of the needle, although it disappears on the level from the axis of rotation when its dimension passes in lower part limit of the resolving power of the eye.
One invites resolving power the aptitude of the eye to separate the points forming an image. This vision is limited by the structure of the retina.
As example, on a screen of computer of 320 millimetres broad and having a definition of 800 points on a horizontal line, the eye can separate starting from a distance from 2 meters a black spot and a white point from 0,4 millimetres from broad each one forming an element of 0,8 millimetres.
Consequently, the eye can detect by far weak displacements of an object or an image.
It distinguishes for example starting from a distance from 2 meters a jump from 0,8 millimetres from a needle from the seconds from a watch.
