Hologram Screens: Bring Those Sci-Fi Displays To The Real World

If you’re a fan of science fiction movies, then you must have seen holograms being used before. Basically, these Hologram screens are cool ways to show imagery that entirely transcend what we know today. 

Now, while the inspiration for hologram screens might have come from science fiction, Advancements in viewing technology have made it possible for us to make use of them in real time. And, their adoption is growing. 

In this piece, we’ll provide the perfect intro to hologram screens and what you need to know about this revolutionary visual technology.

Hologram Screens: No Longer A Sci-Fi Element

Hologram screens are undoubtedly all the rage at the moment. Also known as holographic displays, these are devices that essentially create a three-dimensional image illusion. Essentially, they provide the illusion of images being suspended in space without the need for goggles or any other specialized equipment. 

One of the major characteristics of hologram screens is that they provide opportunities for viewing across multiple angles – even though the images themselves don’t change so much. You could have a static image on a hologram – say, for instance, one that displays a product. Or, you could incorporate an animated piece of content instead. 

Whatever it is, viewing from any angle should bring a nice touch to the overall visual experience. 

It is worth noting that there are some differences between the hologram screens we have today and those you see in science fiction movies. Holograms are looking toward mimicking what you see in projection-based displays. Nevertheless, the ability to provide a more engaging and dynamic view is where holograms shine.

Some of the methods that these screens use to achieve their views include:

The Pepper’s Ghost Technique: 

In the Pepper’s Ghost Technique, you use a semi-transparent surface or a clear glass-like pane to reflect an image on a reflective surface that has been positioned at a specific angle. 

The image or video itself is displayed on the semi-transparent surface with the use of a high-resolution screen or projector, thus causing the illusion of a suspended image that can be viewed from any angle. 

Projection Mapping:

With projection mapping, images or videos are projected onto irregularly shaped surfaces to create the illusion of perspective and depth. 

Essentially, the content is carefully calibrated and aligned with the physical structure of the display surface, thus making the images appear as if they are interacting with the surface and possibly even extending into space. 

Optical Illusions:

There are also hologram screens that work with the use of optical illusions. With special films, lenses, or mirrors, they create the three-dimensional perception, as well as depth and field of view. 

In this situation, screens can use techniques such as parallax barriers and lenticular lenses to manipulate light and create the illusion of volume and depth. 

At the moment, hologram screens are still a nascent technology. And, with the technicals being worked out, there are several steps to go before they reach their potential. However, thanks to recent developments in holographic technology, it has now become possible for these screens to enjoy functionality in multiple industries. Of course, we will be examining some of these major functionalities later.

Breaking Hologram Screens Into Bits

One of the interesting things about hologram screens and displays today is that you get to see them in different types. Generally, some of the prominent options available to you include: 

Pepper’s Ghost Displays: 

We already covered the use of the Pepper’s ghost technique, where a reflected image or video is placed on a semi-transparent surface and theme reflected again on a reflective surface that’s been positioned at an angle. 

These displays are best used at concerns, museums, product presentations, and more. 

Holographic Projection Displays:

For holographic projection displays, projection mapping techniques are used. Once the content has been aligned with the physical structure of the displaying surface, it becomes easy to give the impression of a hologram suspended in space. 

Holographic Optical Elements (HOEs):

A holographic optical element is a specialized holographic film or plate that uses light manipulation to create the perception of 3D images or holograms. 

HOEs can be put into transparent films or screens, and they easily use light diffraction to create different viewing angles and the illusion of depth. They find best application in small-scale holographic displays. 

Lenticular Displays:

These displays combine lenticular lenses and interlaced images to create 3D and depth illusions

With lenticular lenses, you have cylindrical lenses with close spacing that refract light in different directions. When combined with interlaced images, they create multiple perspectives that can be seen as 3D images or animations. 

Holographic LED Displays:

With holographic LED displays, you get an array of LEDs and diffraction techniques that are used to create hologram illusions. 

With accurate light control, these displays easily regulate the emissions of individual LEDs, while also applying diffraction patterns. This means that they will be able to generate three-dimensional images and unique depth perceptions. Think of them like the futuristic hologram green screen, where customization and effects can even be added.

Holographic Headsets and Glasses:

Of course, it is also worth remembering the classic glasses and headsets. They incorporate advanced optics, sensors, and other display technologies to deliver the required projection to viewers. 

These devices basically overlay virtual holographic images onto the real world, creating a mix between virtual and augmented reality viewing. 

Stereotypical vs. Realistic Holograms 

Another significant distinction for holograms will be between the stereotypical and realistic holograms.

Stereotypical holograms are most likely the most common ones we see around. We have options like the Microsoft HoloLens, which launched in 2015 and put the tech company on the map. 

These holographic lenses are widely used today, thanks to their augmented reality features. However, they face stiff competition already from companies like Meta (with the Meta Quest headsets) and Apple (with the recently announced Vision Pro goggles).

With these types of holograms, content developers would need to connect to a form of studio software that allows them to import models from other services or create 3D objects themselves. There is an app interface available that helps them with this as well, making it possible for them to create highly complex virtual objects on their own. 

In turn, the objects are translated to the imagery of the surrounding world, thanks to the use of virtual reality glasses. So, you get an image that looks similar to a rendered product. These glasses make it possible to link augmented reality objects with traditional computer programs, thus creating functionality for both work and entertainment.  

As for realistic holograms, they are a bit older. They date back to 1947, when a Hungarian physicist known as Dennis Gabor developed our modern idea of hologram theory while trying to build an electron microscope. Still, the theory didn’t really hit the ground running until the development of the laser back in the 60s. 

With realistic holograms, lasers emit a potent burst of light that stays on for a few nanoseconds. This makes it possible to get holograms of high-velocity events, which would ideally not be achievable with regular cameras. 

The first known iteration of laser-based realistic hologram imagery was created in 1967, and it paved the way for different other applications of holographic technology that we have today. 

How Hologram Screens Work 

For a quick rundown of how holographic technology works, consider a laser light beam that is split into two. One of these beams is targeted at the image in question, while the other is spread through the recording media. In most cases, the most common recording media will be photographic plates. 

Thanks to the applications of mirrors, the reference beam – that is, the second of the initial two beams – can be deflected on the recording device. 

At some point, of course, there will be a joining of both beams. In most cases, this will happen along the recording medium.Once the recording is done, the next step will be the creation of the 3D picture. Usually, this can consist of three major processes:

  • A step-by-step recording of the content from different angles, thus resulting in a reliable multi-camera capture. 
  • Converting the content into a format that is compatible with the projector itself
  • Possible data manipulations to optimize the recording angle and provide flexibility for viewers.

In the past, we’ve seen cases of holograms that seemingly project images being suspended in air. For these systems, a 3D object reconstruction device – as well as aerial projection equipment – will need to be used. 3D images are created by the reconstruction device, and from there, the 3D hologram is created using the aerial projection device. 

Let’s also not forget electro-holography – a method that can be used to generate images without any excessive mechanical steps. And, revolving mirror systems can also be used to display true 3D images – simply direct a high-speed video projector towards spinning mirrors, and they will be reflected in all directions, allowing viewers to see the three-dimensional images regardless of their angle.

The process of electron-holography can help to result in 3D image projection with minimal steps involved. And, you could even combine this with manipulation processes like rotating mirrors to make the images seem as lifelike and vivid as possible.

Nevertheless, it is worth noting that these screens still have some limitations that you might want to consider. Some of them include:

  • Viewing Angle and Perspective: For now, most hologram screens come with limited viewing angles. This means that the holographic effect itself might only be visible within a specific range or from particular perspectives. If you do view outside these angles, you might end up with a distortion or effect loss. 
  • Image Quality and Fidelity: Hologram screens are still developing image quality. So, you might not get the same fidelity that is available in 2D screens. Research is currently ongoing to ensure that we can achieve high-resolution holographic displays without necessarily compromising on image quality. And, already, some of the hologram screens at NSE LED Cloud offer comparable resolutions to 2D displays.
  • Limited Color Range: Hologram screens usually have limitations when it comes to reproducing a broad color gamut. However, some of them now use diffraction or interference, which can improve accuracy in color artifacts. Things aren’t necessarily at the same level of some other display variants, but developments in technology should address this. 
  • Complexity and Cost: Considering that the technology is still nascent, it should come as no surprise that hologram screens are still comparatively more expensive than 2D displays. Just as well, the steps of installing them are slightly more complex than 2D displays. However, when you consider the benefits of these displays, they definitely outweigh the costs. 
  • Environmental Constraints: You also want to pay special attention to the possible environmental concerns that hologram screens have. These will vary particularly based on the installation parameters, but we can always provide a proper consultation to help shed more light.
