In this article, discover how a holographic projector works, the different models, and our advice for choosing the one that meets your needs.
Introduction to the holographic projector
What is a holographic projection?
One holographic projection is an advanced technique that allows the creation and projection of three-dimensional images floating in space, giving the illusion of real objects or scenes. This technology is based on the principles ofinterference And of diffraction of the light.
When creating a hologram, a laser illuminates an object, while a second laser beam, called reference beam, intersects with the light reflected by the object. The resulting interferences are recorded on a medium such as a film or an LCD screen. This process allows the three-dimensional image of the object to be reconstructed during projection.
Holographic projection often uses reflective mirrors And semi-transparent surfaces to direct the light beams and create the illusion of volume. For example, a holographic propeller can broadcast a virtual image thanks to the rapid rotation of LEDs, while a glass pyramid can reflect a 3D video visible from several angles.
This technology makes it possible to represent not only shape And the color of an object, but also its volume, offering an immersive and realistic visual experience. Viewers can get the impression of seeing real objects floating in space, without the need for a visible screen.
How does a holographic projector technology work?
How does holographic technology work?
La holographic technology used in projectors is based on the principle of light interference. The process starts with a laser beam that is divided into two rays using a reflective mirror.
One of these rays, called reference beam, is directed towards a recording medium, while the other ray, the light beam, is projected onto the object that one wishes to record.
When these two beams intersect, they create interference between the light waves. This interference is recorded on the medium and forms a model containing all the information necessary to reconstruct a three dimensional image of the object.
During the projection, this interference model is illuminated by a light source, thus making it possible to reconstruct the holographic image. Each Holographic pixel of the viewing medium represents an angle of view, offering a realistic and immersive visual experience.
How do you make a holographic image?
Creating a holographic image involves several specific steps. First, the object to be recorded is illuminated by the light beam.
Simultaneously, the reference beam is directed towards the recording medium, often a photosensitive plate. The light waves reflected by the object intersect with the reference beam, generating interference that is recorded on the plate.
Once recording is complete, the plate contains an interference model representing the three-dimensional image of the object. To visualize this image, the plate is illuminated by a light source, which allows the hologram to be reconstructed.
In modern projectors, this technology is combined with LEDs and fans to create dynamic and moving images.
Additionally, holographic projectors use advanced techniques such as holographic cylinders and micro-pistons to improve the resolution and sharpness of projected images. The cylinders covered with LEDs and the micro-pistons activated electromagnetically make it possible to produce three-dimensional images complexes and detailed.
Holographic projector: differences and complementarities
What is the difference between a projector and a hologram?
It is essential to fully understand the distinction between a classic projector And a holographic projector, as well as between a hologram and a simple projection. A conventional projector is limited to projecting images or videos in 2D on a flat surface. On the other hand, a holographic projector is capable of creating three-dimensional images that seem to float in space, without requiring any visible support.
A hologram, unlike a simple image or video, captures not only the intensity of light emitted by an object, but also its phase information. In other words, it records light in all its forms, allowing a three-dimensional image to be reconstructed when properly illuminated.
In contrast, a conventional projection only captures the intensity of the light. Therefore, it cannot reproduce the volume And the depth of the object with the same precision as a hologram.
Technologically, a holographic projector uses components such as reflective mirrors, of holographic propellers or even glass pyramids to direct and diffuse light in order to create an illusion of volume. These elements are absent in conventional projectors, which simply project images onto a flat surface. In addition, holographic projectors are often equipped with LEDs, fans, and WiFi connectivity systems, which improve the quality And theinteractivity projected images.
In summary, the main difference between a conventional projector and a holographic projector is the ability of the latter to produce immersive three-dimensional images. This technological advance opens up innovative perspectives in various fields such as publicity, art or even education.
Choosing the best holographic projector
How do I recognize a good projector?
Choosing the best holographic projector involves considering several key criteria. First of all, the solving of the device is essential for obtaining accurate and detailed images. A good holographic projector should offer a High resolution, making it possible to visualize minor details and small texts without distortion.
La luminosity is another essential component, especially if you plan to use the projector in bright environments. Good luminosity ensures a optimal visibility, even in broad daylight. Projectors equipped with LED light sources are often the best choices in this regard, as they last longer and maintain their brightness over time.
La compatibility with your devices is also important. Make sure the projector is compatible with your computers, tablets, or smartphones, and that it supports the file formats you use.
In addition, a ease of installation and usage is a significant advantage, as it reduces the time and effort required to set up and use the device.
Finally, the lifetimes of the device is a criterion that should not be overlooked. Opt for projectors built with quality materials and offering a minimum lifespan of 5 years. This ensures that your investment will be both profitable and durable.
What are the best projectors?
The best holographic projectors vary depending on your specific needs and your budget. For marketing and advertising applications, choose projectors with advanced features such as WiFi connectivity, Bluetooth, and a mobile application compatible with iOS and Android.

La lifetimes of a holographic projector is an essential criterion to take into account when buying. It not only determines the sustainably, but also the long term value of your investment. Recent models of holographic projectors are designed to offer a remarkable lifespan, mainly thanks to the use of high quality LEDs.
On average, the LEDs used in these devices can reach a lifespan of up to 100,000 hours. This is a much better performance than other lighting technologies. For example, a projector equipped with LED beads can work continuously for around 11 years if used 24 hours a day, and even longer if used intermittently.
This impressive longevity is based on the use of sturdy materials such as ABS, PC, and aluminum alloy. These materials guarantee a shock resistance And a thermal stability exceptional. In addition, integrated cooling systems play a key role in maintaining a stable temperature, which helps to preserve internal components.
