One of the greatest football players in history is filmed as he brings to the mind his career in the '60s, in one of the most prestigious clubs in Europe.
In a section of the museum of the football club, the video is reflected in a ZHM - Holographic Mirror. The footballer tells as if he were present, while behind him you can see the trophies and the videos of historic matches.
The ZHM - Holographic Mirror, 3 m wide and 3,3 m high, is installed with an angle of 45° and reflects a video that is projected horizontally on the ceiling.

It is a transparent mirror for the holographic reflection of a video projected on other surfaces (Rear-projection screens, Frontal projection screens, monitors) or of real subjects.

It allows the superimposition of the reflected image on a real background with a three-dimensional effect.

The adjustment of the brightness of the video reflected from 0 to 100% and vice versa allows to display or hide the reflected subject (hologram).
The effect is also known as the Pepper's Ghost effect and was described for the first time by Giambattista della Porta in 1584 and subsequently by Athanasius Kircher.

The transparent QHM - Holographic Mirror Film with which it is made prevents the duplication of the reflected image that would be obtained with the use of sheets of glass or plexiglass.

The holographic image is not obtained with a direct projection on the ZHM - Holographic Mirror but with the reflection and the projection, therefore, does not reach any of the zones that can be watched.

Frame
1 - made of Aluminium trusses
2 - a custom made 9TM - Frame for scenography
The flexion of the frame has to be imperceptible or it won't be possible to adequately stretch the mirror that will show folds and deformations of the reflected image.
The mirrors have to be stretched along the four sides in a uniform way.

Perimeter
and dimensions
of the mirror
1 - WCS - Strap + WOC - Eyelets + WPE - Perofix 27 cm
In this case the mirror must have a size of 5 cm per each side less then the inside area of the frame to allow the correct stretching of the WPE - Perofix 27 cm.
It is needed a perimetric masking, whose dimensions have to be of 20 cm per side less than the inside area of the frame, in order to hide the creases due to the punctual tension of the elastic hooks on the eyelets.
2 - pocket + 8FV - Glass Fiber Rod + WCG - Ratchet straps
For experienced users, it allows to avoid the punctual tension of the elastic hooks on the eyelets but it however needs a perimetric masking whose dimensions have to be 20 cm per side less than the inside area of the frame.
