As we all know, in this era technology evolving at a frenetic pace; tomorrow we were talking about 2D and 3D, and today we are introduced to 7D holographic technologies. Which are being drastically used in different first-world countries. 

So In this article, we are going to talk about what Is 7d Hologram and How 7d holograms are made? First of all, A hologram is capturing and records the light field instead of images and projectors screens that can be viewed without the aid of special glasses or any intermediate optics. It scattered this recorded pattern of light in this way it presents the resulting image.

We capture not only the reflected intensity of the objects but also their phase. As a result, a 7D hologram is a technique for capturing a high-quality hologram with seven parameters.


A 7D hologram is a technique for capturing a high-quality hologram by combining seven dimensions. In three-dimensional space, viewing direction is captured in a two-dimensional space from each perspective, as well as time and light qualities for each viewing direction.


The main difference between 3D and 7D hologram technology is that 7D holograms are created from a large number of different angles that surround a person or a scene. Seven dimensions or parameters are referred to as 7D.

Each location is defined in 3D space, and this position corresponds to the viewing direction in 2D space. There are two more factors for each direction: time and intensity. The resultant image moves as viewers move if stereopsis and depth perception are recorded simultaneously.


The Reflection Hologram:

Object and reference beam incident on holographic film is on opposite sides. This type produces high-quality images and is thus very expensive.

Transmission Holograms

On holographic film, the object and reference beam are incident on the same side. When something is mass-produced, it is less expensive.

A transmission hologram is often seen using laser light of the same sort that was used to make the recording. The picture is conveyed to the observer’s side by this light, which is aimed from behind the hologram. The virtual picture can be extremely detailed and crisp.

Hybrid Holograms

Real objects are not required. Computer algorithms are used to calculate an interference pattern digitally. Many modifications can be made between the reflection and transmission types of holograms. Computer-generated holograms are one of them.


First of all, it is not too complicated to build a hologram 7d projector at your home. As it can be used to teach kids basic knowledge with the help of unique holographic features.


  • Plain paper
  • Pyramid template
  • Piece of acetate or CD case
  • Black marker pen
  • Scissors
  • Sticky tape
  • Smartphone with hologram app

Why Does this Work?

4 distorted images of a 3d model are displayed on the phone screen. These are reflected on the four sides of the pyramid. When the pyramid is viewed straight on, the 4 separate reflections come together to produce one 7d image.

Advantages Of 7D Hologram: 


It improves the practicality of objects, including depth.


As previously said, they are complicated patterns that provide security in a wide range of applications.


 It allows you to create many pictures on a single plate, including 7D images


Other technologies can be simply coupled with holographic technology.


It does not necessitate the use of special glasses and may be viewed from any angle.


Cannot be recreated, since it’s difficult to change or transpose on a larger scale.



It has a greater manufacturing cost than 3D projection and is difficult to view in the presence of fluorescent lights. The use of the notion of holographic projection in the design of products is costly.

The future of holographic technology:

The future of holography lies at the intersection of AI, digital human technology, and voice cloning. The consistent increase in worldwide computing power will allow for the creation of digital human models that will render at an ever-accelerating pace that will make them more and more difficult to tell apart from real ones.

In turn, the evolution of holographic technologies will lead to their increasing availability and portability. Imagine if holographic content could one day be as accessible as streaming content: holographic cinema, holographic theater, music shows.

Augmented reality will no longer require wearing special glasses but will be directly integrated into landscape objects. We already know how holographic pedestrian crossings and holographic advertising work. But we can only imagine how our cities and lives will be changed as the evolutionary pace of technology continues to accelerate.


What is a 7D Hologram?

7D hologram is a technique for capturing a high-quality hologram by utilizing seven characteristics known as dimensions. Viewing direction is captured in a two-dimensional space from each perspective in a three-dimensional space, and time and light attributes are captured for each viewing direction.

How much Hologram Projector Cost?

Projections start at 13 x 13 feet, which costs a minimum of around $18,113. The largest projection they have full pricing info for is 13 x 32 feet. That would likely cost around $32,453. Of course, West may have also rented out an arena for the hologram, which would be an additional expense.

Do Hologram Projectors Work?

Holographic projectors generate projected images using holograms rather than graphic images. They use a specific white light or laser light to shine on or through holograms. A smartphone may use such a projector to produce a picture for the viewer in an empty area rather than on a small screen.

Will There be a Hologram in the future? 

A new method called tensor holography could enable the creation of real-time holograms for virtual reality, 3D printing, medical imaging, and more. The technology can also run on a smartphone. It’s predicted the technology could bring commercially available holograms within reach.


A  hologram is a limitless technology that will transform every part of life as you can imagine. If we look at the alternative effects of this technology, then it can be no more harmful than any other technology,  such as it can be used for military purposes, achieving a conspiracy that might lead to conflicts.

This technology with its full implementation can bring historical change in every field of life. The possibilities are truly exciting! This technology is still in its working phase. When it is going to implement, it’s not wrong to say with 7D hologram technology we can view the world according to our imagination.
