Hologram projectors and their applications.
It should be understood that the hologram is not simply a video or an image that is taken without any optimization.The technology of the holographic propeller type holographic projector is based on direct projection by LEDs that work on the same principle as a television. This means that the light is directed directly at the viewer. The difference compared to the conventional screen is when the viewer wants to display a very pure black color. The screen will completely turn off the LEDs to show black while a hologram will give you transparency.

Hologram Projectors, a bit of history...
Holograms require the mastery of complex techniques, such as the interference of light waves. These techniques have undergone significant development over the past few decades. The ancestors of holograms were first used in theater in the 19th century and were called Pepper's ghosts, named after the British scientist. John Henry Pepper. A window was placed in front of the stage and an actor dressed as a ghost moved into a hidden room, which was then projected onto that same window. The transparency and reflections of the glass made the audience feel like the ghost was on stage. Pepper's Ghosts have long been used to bring ghosts onto the theater stage.
What is the best technology for a hologram?
There are a multitude of technologies but they are grouped into two main principles:- Direct projection: lHolographic propeller technology or transparent screens.- Indirect projection (or said by refraction) : which includes all other hologram technologies such as pyramids, stretched canvases, water vapor holograms, and other inclined glasses.At Holovisio we have chosen to focus above all on one of these technologies that is for us, the most promising, the most versatile hologram technology with a striking finish. Here's for you The holographic propeller.So why did this choice be made to other projection methods? Well, first of all because we are in a case of direct projection and not by refraction. This means much greater luminosity and vibrant colors. that we will not be able to find in a pyramid projection or water vapor for example. In addition, these advantages in terms of luminosity and colors allow the holographic helix to be used in many situations without having to be immersed in a dark atmosphere as in the case of refraction. In other cases, your support (the glass on which your image is projected) absorbs a good part of the luminosity emitted by the screen placed below.There are therefore significant concerns with all refraction technologies that can emit reflections in the display surface, but which will also be much more complicated to integrate in situations of normal or significant luminosity. Transparent screens are currently an interesting alternative, although lacking in performance since they remain visible structures that ruin this 3D effect and the transparency sought in the hologram in cases of use in high luminosity. These screens still remain relevant in cases of projection on stage in a dark environment, as evidenced by the concert of'Eric Prydz unto Tommorowland 2022.

What are the uses of a hologram projector?
In fact, holographic projectors are constantly being renewed, based on new technologies made possible by technological evolution, even if the principles are over 100 years old.The applications are truly infinitely customizable and the possibilities are still untapped. The variety of applications of holograms proves that they can be used in almost any field, with no limits to the imagination. They are increasingly used in communication campaigns, for example on the signage of brands and commercial premises. The fact that the medium is increasingly accessible suggests that holograms will probably replace ordinary screens. Holograms have become a central part of strategies of corporate events and marketing because of their incredible power of seduction.In the various areas of use of these holograms, we find in particular:
- The Scenography
- The Showroom
- The Automobile
- The Industry
- L'Hôtellerie
- The leisure parks
- La Santé
- L'Art
- The event
- The Transport
- The Policy
- The Culture
- ...
The holographic propeller offers you numerous advantages:
- Modular: The propellers are of different sizes to meet all projects
- Efficient: No loss of luminosity because the light source is directly the propeller
- Economical: The holographic solution with the best quality/price ratio
- Customizable: Easily broadcast what you want in a few moments
- Intuitive: Can be easily used by anyone and in all conditions
It is a revolution in the world of communication as the benefits are significant and the solution accessible to all audiences. And we are proud to contribute by offering you this opportunity for your business.I WANT A QUOTE FOR MY PROJECT
