The future is bringing an rise in technological creations that helps us the around the globe. Recently, the development, and study, of the creation of human-like holograms are being tested by companies like ARHT Media, Imverse, and Spatial- with a great success. Holograms can connect people virtually with the ability to have a live interaction, witnessing what is happening during the hologram, and it’s highly beneficial in the world.  

The Science Behind It

First, we need to understand the basic science behind creating a hologram that can display an image. They are sometimes nicknamed “photographic ghosts.” A hologram is a virtual three-dimensional image of an object that is created through information stored in a holographic plate that displays the image. All basic holograms work by recording a pattern of light that is interfered with by an object and illuminates it, using light patterns. With the creation of human-like holograms, the technology is a bit different. Scientists and developers from ARHT Media use the projection of a single laser which is diffracted into two light waves, then travels the same direction by shining it into something called a “half-mirror.” This is a piece of normal glass that is coated in a very thin layer of silver that allows half the light to reflect and the other half to pass through. One of the light beams reflects onto the object that will be the hologram, then hitting the photographic plate called the object beam, while the other light beam hits the photographic plate from the opposite reflection, called the reference beam. To create an animated hologram, the light beams need to be constantly flashing and the object would have to be rotating and captured by cameras for the hologram to animate just like a video with multiple frames being displayed quickly. People can view the hologram from any angle due to the reflection of light using lasers and 360-degree cameras. The companies have created software that allows users to communicate with a hologram. If any person walks up and asks the hologram a question, it would have a microphone input, speech to text modules, and voice recorded collections of the human-like hologram. It would return with a response and with a virtual motion of the hologram. 

Use In Modern Day, Future, and Post-Pandemic

With this creation of holograms, different companies were inspired which led to the creation of holograms that would be able to display a certain area. This is nearly like virtual reality, but displayed through a holographic plate. We never know what the future has in store for us, and there will always be obstacles that will need the creation of new technology. Holograms are extremely useful, from being used in medicine to basic communication, with others around the world. Not only is it currently a benefit for those industries, but it could be a benefit after the pandemic. Will the use of human-like or three-dimensional area holograms be used for future education and work? We will find out sooner than you think.
