The hologram: what is it and how does it work?

As specialists in the latest generation of holographic technology, we decided to offer you this quick and comprehensive introduction to the hologram, an incredible technology and which is the future of communication. Step into the future!

Let's get into the subject...

In a nutshell, what is a hologram?

A hologram comes from holography. Etymologically, hologram comes from the Greek “holos” which means “in full” and from “graphein” which means “to write”. So that would mean “write in full.” This is indeed the case because here we are putting a photograph in volume (in full). We then call it a hologram, a 3-dimensional image that is broadcast with the impression of suspending in the air without any support. We may disappoint some, but the hologram still requires a medium of any kind. The ones you can see in the movies that appear in a complete vacuum are just science fiction. But let's stay hopeful, it's coming soon, let's hope!

We still need support to this day. We haven't yet managed to do without it like in sci-fi movies. But let's stay hopeful!

We have always used the word hologram on a daily basis to describe certain 3D content that is placed on 2D supports. As a result, you have 3D content by playing with the angles of view but without the effect of floating in the air. Hologram technology has been present for a long time on many daily media in order to ensure their security (bank cards, bank notes, etc.). They are complex enough to limit their reproduction.

Also, toys for children in the form of fans appeared and made it possible to broadcast an animated message with the impression of being in a vacuum. These were just simple toys, with an unappealing look and not advanced enough to be as recognized as they are today. But they have played a major role in achieving technological advances in this sector.

Don't confuse all hologram technologies. This term is used in our vocabulary to describe things that are not things but just 3D effects.

Now it's time to find out what's available to you today. We have in fact seen that since the broadcast of the hologram of Jean-Luc Mélenchon during his meetings at 7 different locations or even that of Tupac during a concert after his death, the subject is very interesting and intriguing. It is not surprising, when you see the rendering of this technology and its innumerable applications, that it is beginning to make a growing place for itself in the Point of Sale Advertising (POS) sector.

But to answer all your questions, we are going to look at different technologies together. Among them, we have A favorite to share with you. It is undoubtedly the best holographic solution because it is inexpensive and offers an ultra-realistic rendering. Come on, we'll tell you more later

The main current holograms for you!

The holographic propellers

Let's start directly with the best. The most recent solution of all and also the most impressive. It requires advanced technology and quality equipment for a hologram with an ultra-realistic result.

The principle, however, is quite simple. The holographic helix is finally like a propeller that can have 2, 4 or 6 branches. In general, the number of branches increases as a function of the diameter of the propeller. Just like a propeller, when you turn on the system, it starts to turn. The speed of rotation of the propeller is such that you no longer see the branches. Each branch contains a light strip composed of numerous LEDs (more or less depending on the definition). These LEDs then turn on and then project your visual. You are probably wondering how this is done while things are spinning? Well that's where not all products are equal in terms of quality. It is an internal processor that is responsible for lighting each LED at a very high frequency at a specific moment in the cycle. It then calculates the rotation speed as well as the distance between the LED and the center of the propeller to perfectly diffuse the image. It is imperative for a quality result, to have the most efficient products in your possession.. Image definition, frame rate, internal processor, compatibility, rotation speed... All criteria that are mandatory to take into account and that we were able to see for ourselves when using the propellers holographic.

This technology does not use the refraction system but rather acts as a hologram projector. The image is directly projected by the support. It is the rotation that ensures the impression of floating in the air. The The result is incredible and spectacular because it is impossible to see the branches and your animation floats in the void.

The holograms through the holographic helix are at the same time very inexpensive, compact and easy to set up. However, the creation of holographic visuals requires special treatment so that they are of the best quality and adapted to the propeller. But once done, you can enjoy!

The technological prowess of the holographic propeller goes even further because you can use this solution in all sectors and everywhere! On a wall, a store front, a living room, a wedding... And even a big concert! You're going to tell me it's too small isn't it? Well no! Some models like the HV EVENT 65 that we propose, is compatible with multi-helix synchronization. Do you want to create a holographic wall of 4 helices by 5? It is possible and the hologram will therefore be just incredible and huge, specially adapted for the size you have chosen.

Suffice to say to you that this technology is really changing the codes of holography because it is totally different and above all good. more economical for an even more realistic result that adapts to all needs.

On stage (like the Snoop Dogg concert with Tupac)

This is the most traditional solution. It is technically simple to understand because it mainly plays on 2 levels of depth. You use a projector to project the holographic animation onto the first support (a bit like a window because it must both capture and reflect the image projected to the audience but also allow you to see the background for the depth effect). The real difficulty is to find a glass that allows as much transparency as possible but reflects the hologram as much as possible without any reflection.

In the window and pyramid

This technology is still very current and widespread. We finally use the same base as the hologram on stage but we add a different system. The box that you can see will act as a stage AND a projector! Yes indeed it will integrate the projector directly into it. The window we were talking about just before is back but this time, it is changing its positioning. Are you wondering why? Simply because the hologram projector is no longer frontal but placed above or below. The advantage is that the spectator sees absolutely nothing of the broadcast, that everything is played out in a space where he cannot interfere (unless he decides to put his hands in the box and block the projection). And the fact that there is a height between the glass and the projection adds that same depth to the final hologram you see. Thus, with the refraction of the visual on the glass, the hologram regains its verticality in the eyes of the viewer. Hence the 45° angle of the glass.

For the window, it is a single projection and a single window. However, it is visible only in front of the box. However, the pyramid projects 3 visuals, each towards a window. So you have 3 angles of view for the same hologram.
