When looking at a holographic display, the brain is instantly tricked by the illusion of having a physical object or real environment mixed with the three-dimensional digital overlay. The visual experience immediately evokes emotions and triggers the senses to fire up the activity in the cortex, essentially making the viewer process and retain the information that is communicated better. Thanks to the smartphone revolution of the past decade, the human attention span is at a historically low level.
People need a real reason to snap out of autopilot and look up from their handheld devices. In other words, you need to provide something that evokes emotions, creates an experience and bring that little spark of unexpected magic. In essence, a holographic display works by having a high-definition or 4K screen reflect digital content through glass with special coating, called the glass optics.
When placed at a certain angle, the glass optic will create an illusion that makes your brain interpret the digital content as three-dimensional. Holographic Spinning Mirror Technique A simple, yet effective solution. Pros Creates an effective optical illusion of a 3D hologram. Efficient in displaying a 3D version of a video to a specific scale.
Cons Introduced in , this technology has seen very little development since then. It is limited in size to the device, which restricts its usage. Semi-transparent OLED screens In recent years, serious investment has been made into transparent OLED screens by some of the biggest names in electronics manufacturing. Pros Very new to the market, the technology is still rapidly developing and new versions are imminent. Creates a contemporary way of displaying content and gives a little more flexibility.
Provides a bright platform for displaying content. Cons Images displayed are 2D illusions of 3D images. Holographic Pyramids These popular holographic solutions come in two types: the DIY holographic pyramid that you can place on top of your smartphone or tablet at home, or the infinitely more professional constructed holographic cubes, also containing a pyramid alongside a screen, that are sold online by many retailers.
While the technology is impressive, there are pros and cons for users. Pros Creates a holographic illusion that makes the image on your screen appear as if it is a 3D hologram.
This type of installation can be made professionally or recreated for home entertainment purposes using homemade constructions. Cons Only works on a small-scale and is limited to the size of the enclosure, pyramid, and screen involved, current maximum size is around the size of a table.
Results vary. Professional pyramids produce much more realistic results than DIY versions, which look more like a reflection rather than a 3D image. Such technology must remain inside the cube or pyramid, making it difficult to scale or transport, limiting its usage. Pros This is as close to a true 3D hologram as society has got — a complete 3D volumetric image. The technology is ground-breaking and may pave the way for future advancements.
Cons This is only for the lab technology, due to the use of lasers. While the results are pretty spectacular, at the moment the technology can only create small, simple images, so we need to keep that dream of Blade Runner style holograms for another day.
The only limit is your imagination. Displaying quality content of epic proportions, the Wall expands the potential for businesses to create displays that cause their viewers to stand and stare in pure amazement. To help you learn more about the advantages and disadvantages, here are some of the pros and cons: Pros An all-in-one holographic system that combines 3D content with software and a hardware device that creates holographic displays.
Allows you to create your own custom content using the online 3D Studio or get custom content to order. Cons While no system is entirely flawless, the only downside to using HYPERVSN is the necessity to maintain a high level of breathtaking 3D content for the solution to have the desired effect on your audience.
However, a solution is offered through the system so that users can create content themselves with our 3D Studio. We also offer users the opportunity to order custom content form our Design Lab or from one of our official worldwide Content Creation Partners.

Smalley hopes to improve the size and resolution of images by a factor of three or four in the near future. The real trick, he said, will be getting multiple projection systems to work in parallel and will allow for images much larger and more detailed that what can be generated now.
Famous last words, I know. For now, Smalley said he will be content if he can just get people to stop calling his images holograms. It would make our lives a lot easier if we could improve this one thing. Skip to main content Gadgets. Seeker Indie. Social Media Links. There are three major steps involved in a 3D image reconstruction and the steps are as follows.
The system requirements for 3D hologram projection in the mid-air consist of a 3D object reconstruction device and an aerial projection device. The reconstruction device creates a 3D holographic image.
Further, the aerial projection device projects a 3D hologram in the mid-air. Electro-holography can project 3D images aerially without any use of multiple projectors and mechanical processing. A spinning mirror system is also used to project a true 3D image. A high-speed video projector is aimed at spinning mirrors that reflect in all directions, making it possible to view images at any angle in 3D.
The interference patterns recorded using single-wavelength light leads to a monochromatic hologram. Multiple interference patterns are recorded with different wavelengths to create a colour hologram.
Then, holographic projectors use lasers with different wavelengths to illuminate the corresponding interference patterns for their respective colours. There are many applications of this technology spanning different sectors. Few application examples are listed below. Hologram Technology What is Hologram Technology? History of Hologram technology In the late s, the Nobel prize winner Dennis Gabor invented and developed the holographic method. In the year , Yuri Denisyuk was able to achieve practical holograms that recorded the 3D objects.
