Possibilities of 3d Hologram
In modern times, 3D holograms are not just possible; they are already happening. With the power of modern technology, it is now possible to display three-dimensional holographic images that you can interact with in space. The recording and playback rendering of 3D holograms was made possible by a recent series of advances in computer science and computer graphics.
Companies like Microsoft developed the Kinect camera for Xbox controllers and cameras to detect the movements of humans. The technology is used in TVs and games that allow users to have a more realistic experience of 3D images. But even with this technology, it seems that a true 3D hologram has been left out in the cold despite years of development.
Some companies are developing this technology, but there is no shortage of stops as they try to establish their own. 3D hologram companies include Meta and PolyHeme, which have worked on holographic technology since 1991. They have been researching the technology for more than 30 years with little success.
What is a 3D Hologram?
Holograms are actually not a new concept. Holography is an optical technology that uses lasers to make a three-dimensional image of an object. It was first invented in 1947 by the British scientist Dennis Gabor and has since been used in high-level applications like aerospace and medicine.
A hologram is made up of two elements: the hologram pattern and the light source. These come together to make a 3D image that looks like it is floating in the air.
Modern Developments In 3D Technology
A company called LucidCam has launched a campaign to raise funds for its 3D holographic camera. The camera is designed to make it easier for users and developers to create 3D holograms. The company hopes that the funding will give them time to develop their final product.
Long 3D holographic movies, virtual reality, and augmented reality games have all been promised soon, though it seems that there is no way to create a true 3D hologram in real-life circumstances.
However, this year, the “world’s first” 3D hologram was shown at an event in London. Various companies have tried to produce this technology with little success in the past few years. Most of them are pretty expensive. Some require a camera to capture movements and a screen to project the image that creates the illusion.
Limitations in 3d Holograms
There are currently no companies in possession of the technology necessary to create a true 3D hologram. Most 3D images used today are not actually “holograms” but rather stereograms, which are 2D images that deviate our brain into visualizing 3D holograms. It has been proven that people can see three-dimensional objects when shown forward and backward, where the image also goes into peripheral vision.
Obstacles in Using 3d Hologram
It is quite expensive to develop 3D holograms with the equipment needed to capture movements in 3D. A system has to be developed to record activity, and the software uses that digital information to recreate the image.
Some things are still unknown or unclear about this technology. The hologram’s position and motion must be well-calibrated before it is launched into the air. Otherwise, it will not look good enough.
There are also doubts concerning whether the 3D holograms can work over large distances, so it is still unknown how this technology will be applied.
3d Hologram in Films
Nonetheless, there have been some film applications of the technology. The idea of a 3D hologram was first used by the 2009 movie Star Trek where an image of Vulcan was projected, and a perfect likeness was achieved. In another film, 2012’s Avengers, Tony Stark creates a living, breathing Ultron using simple 3D images. Though Stark’s prototype failed the first time, it worked out on the second attempt.
Still, many obstacles stand in the way of creating a genuine 3D hologram. Even if it were possible to send a digital image into the air and recreate itself in life-like dimensions, it would still be impossible to create solid objects without advanced technology. If humans were ever to develop that kind of technology, they could create artificial beings for entertainment or even as tools for work.
Though it is impossible to create a 3D hologram in real life, there are undoubtedly many possibilities of using it in the future. Despite a lack of evidence to prove that it is possible to create one, the technology is still on the drawing board, and companies continue developing and researching.
Q. Is it possible to have a 3D hologram that you can touch?
A. No, this is not possible. If it were, then the actual 3D image would be captured in two dimensions with just a video camera. A lot of work would need to make the situation right for capturing a 3D image, and it would take too long to print out on paper. Also, the hologram would be pretty small.
Q. What kind of a device would you need to capture and project 3D images?
A. A video camera or a webcam. These devices are the ones that capture moving images from their surroundings. The computer then has to process those images to recreate the required image. So, in reality, it is a virtual camera able to use all the information captured from outside and create something new.
Q. Can a 3D hologram be called real?
A. No, but it can be relatively realistic. It should have the capability of changing its position and motion as per the surroundings. However, it would need to have all these things for a viewer to believe that this is not a computer-generated image.
