3D Hologram has gradually come from fiction to reality in recent years, and it is more and more widely used in life. 3D Hologram’s unique charm makes people give it more attention, why is it so attractive? Let’s find out together.
Definition of 3D Hologram
3D Hologram is to utilize light source and certain technology to arrange 3D projection to form three-dimensional image in space.
The three-dimensionality of holographic technology creates brand-new possibilities for the display industry. Compared with ordinary two-dimensional display images, 3D Hologram’s imaging allows the audience to walk around at will, and no matter how it is viewed from any angle, its imaging is real and three-dimensional.
How 3D Hologram works
3D Hologram utilizes light diffraction to form a three-dimensional image display, which usually does not require any external equipment to assist in achieving a 3D viewing effect. The holographic technologies that currently exist are laser, electro-holography, HPO, and micro-electromechanical systems, which vary from technology to technology, and the principles of its display vary.
What is needed to display 3D holography?
Holographic Display
As the source of holographic projection, it transforms and creates the base light source for the stereoscopic image, and completes the projection display of 3D Hologram.
Content
When creating a 3D Hologram, it is also important to confirm the suitability of the content in advance; some content is too technically difficult for a 3D Hologram.
Real objects projected by the hologram
Having a real component to surround the projected image can round out the optical appeal of a 3D Hologram.
Pros and Cons of 3D Hologram
Pros
Immersive experience
Developers are currently working on allowing users to have more interaction with the 3D Hologram, which will make them more engaged in the experience.
Enhanced Visualization
Some items or technologies can be difficult to show with true accuracy with just ordinary text and images, using 3D Hologram will allow you to visualize the information you are trying to convey, 3D Hologram helps with information exchange and understanding, which makes it ideal for imparting knowledge and technology.
Versatility
3D Hologram has unprecedented flexibility and creativity, and its application in various industries is often subversive to our knowledge, for example, using 3D Hologram to display deceased singers and actors in front of the audience, so that people who did not exist can re-enter the public’s view, and satisfy the audience’s thoughts that are difficult to be consummated.
Disadvantages
High production cost
One of the reasons why 3D Hologram is not yet popular is that it is quite expensive to produce. The 3D molding of a single image requires a lot of time and effort to complete, and while large corporations still have the capital to try it out, small businesses can hardly afford these costs and are unable to participate in the development of this technology.
Technical limitations
At present, the development of 3D Hologram has not yet reached a very mature level, the relevant researchers are also relatively few, so the process of technological breakthroughs is relatively slow.
Energy Consumption
3D Hologram is a very complex technology, and the complexity of the components leads to high energy consumption.
Comparison with Traditional Display Technologies
Depth perception
The depth characteristics of a two-dimensional image are not obvious, and it is not spatially displayed as well as 3D Hologram.
Audience Engagement
3D imaging always attracts people’s attention more than 2D, so 3D Hologram will increase the time they spend watching, and audience engagement will be higher with 3D Hologram than with 2D.
Interactivity
3D Holograms are more interactive and fun, with the addition of many new interactive designs, 3D Holograms tend to contain more information and allow the viewer to grasp more concepts.
Viewing Angle
While 2D images have a viewing angle restriction, 3D Hologram has no viewing angle restriction, you can look at it from any angle and it looks great regardless.
Types of 3D Holograms
3D Hologram Fans
3D Holographic Fans mostly use LEDs to create the light source for imaging, which can also be called 3D Holographic LED Fan Displays. It utilizes the Pause of Vision (POV) technology to display a series of static images so quickly that the human eye and brain cannot synchronize with the ever-changing rate of the images, resulting in a visual illusion that creates a dynamic 3D Hologram.
3D Holographic Invisible Display
3D Holographic Invisible Display also utilizes LED light-emitting to form an image, which is seen by the human eye, and the brain automatically combines the screen’s front, back, left and right directions to ultimately form a 3D Hologram.
Holographic 3D display has the characteristics of ultra-thin, high definition, high brightness, high transparency, and can be integrated with transparent glass, there will be a very strong sense of three-dimensional levitation in the imaging.
Naked Eye 3D Holographic
Naked eye 3D holographic display is the use of 3D LED display with 3D material to realize the naked eye effect. This naked-eye 3D holographic effect can be realized without the use of 3D glasses, and is currently a very popular way for many advertisers.
Handheld 3D holography
Handheld 3D hologram has the advantage of being small and portable, it is currently the smallest holographic projector on the market, the use of handheld 3D holographic design and imaging is relatively simple, easy to operate, suitable for small gatherings or personal entertainment used to display 3D Hologram. Handheld 3D Hologram is inexpensive and suitable for most users’ budgets.
Head-mounted 3D Hologram
Head-mounted 3D hologram is a wearable device, unlike other 3D hologram devices, it delivers 3D hologram directly to the user individually, its advantage is that it is portable and allows the user to experience the image in a more immersive way, head-mounted 3D hologram is mostly used in gaming, simulated worlds and professional training.
Large 3D Hologram
Often used at large events, large 3D holograms are capable of projecting very large images with very high resolution. Large 3D holograms are more complex to design and manufacture in order to ensure a high quality image.
Applications of 3D holography
Education and Training
Only from the text to recognize the textbook knowledge for students is more difficult, when 3D Hologram used in education, can be complex objects or images to achieve 3D, so that the content of the conveyor is more intuitive, easy to be understood by students.
3D Hologram is also able to interact with students, allowing them to participate more actively and fully.
Marketing and Advertising
In the advertising industry, the main goal of marketing is to attract the attention of potential customers and increase their interest in the product.
3D Hologram, as a relatively rare display technology in the market, is usually only heard of, but rarely seen in reality. When a 3D Hologram is displayed in front of you, most people will be firmly attracted to it.
The 3D Hologram is used in advertising and marketing to have a significant impact.
Medical Imaging
The combination of medical imaging and 3D Hologram can visualize internal organs or parts of the body that cannot be viewed from the outside in 3D, which greatly facilitates the doctor to examine the patient’s internal diseases and injuries in more detail, and to complete a more appropriate treatment plan.
Entertainment
Every veteran gaming enthusiast is dreaming of a real combination of 3D Hologram and gaming, which can be seen from the emergence of many holographic gaming-related novels and movie and television works in recent years, and everyone is full of expectations.
There are already developers using camera and sensor capture to create realistic models to display 3D Hologram in games.
There are even some music concerts that create 3D Holograms of anime characters or real singers, bringing a new kind of 2D and 3D interactive experience to the audience.
Conclusion
The versatility and innovation of 3D Holograms brings unlimited possibilities to the display industry, as these amazing displays require complex production. But high complexity also means high price, which is prohibitive for many.
In this case, its combination with LEDs creates many more cost-effective products, giving 3D Hologram more advantages and possibilities; 3D Hologram must be the future of display technology!
