Holographic Projections – What Are They and How Do They Work?
Holographic Projections, otherwise known as Holograms, have been around for decades and have mostly been associated with futuristic fantasy worlds. As technology progresses, holograms are becoming an increasingly common sight, especially in the entertainment industry. Case in point, you’ve probably heard or even seen the Tupac hologram performance at the 2012 Coachella Music Festival – a performance that’s still talked about to this very day. While 3D technology has come a long way since that iconic performance 8 years ago, holographic projection still faces considerable barriers to achieve the level of realism shown in films and TV shows. Nevertheless, groundbreaking progress has been made, and we’ll be covering that later. But first, let’s take a quick look at what holograms are.
What are Holographic Projections?
Holograms are essentially 3D images created through a complex series of reflections. Perhaps the simplest example of a hologram is on your credit card or driver’s license, where holographic images are commonly used to prevent forgery. Though, that’s not the type of hologram we’ll be focusing on today. The holograms we’ll be referring to are created using the same fundamental principles, yet the technology behind them is a little more complex. That is, they’re holographic projections created using 3D projectors.
Different Hologram Techniques
Over the years, a variety of different types of holographic projection techniques have been developed. These include the simple, yet extremely popular “Pepper’s Ghost Effect,” which works by reflecting images off of sheets of glass and has been a staple technique ever since it was first conceived centuries ago. In fact, it was the very same technique used to create Tupac’s hologram at Coachella. This technique, however, is far from ideal as aspects like positioning and lighting need to be carefully considered to avoid obscuring the image.
Another technique commonly used is Fog Screen Projection, which works by using fog machines to generate a “screen” onto which holograms are projected. This creates a dramatic hologram commonly seen in theatre and haunted houses. While fog screen projection may work well in those particular settings, it holds little value for real-world applications. What’s more, it’s susceptible to interruption by external factors, such as lights and wind, making it impractical to use outside of enclosed spaces.
Last but not least, one of the most recent and hottest holographic projection techniques involves the use of a thin, almost sheer 3D projection gauze, more commonly known as Holo Gauze. Holo Gauze is basically a form of theatre gauze coated in a highly reflective metallic coating. What this means is that it can effectively reflect projections without blocking whatever is behind it and isn’t as affected by external factors as the other two methods we’ve mentioned. This allows for incredibly realistic holographic projections that can appear and disappear out of nowhere. Moreover, this groundbreaking technique is much more portable and affordable than past techniques, making holographic projections accessible to practically anyone.
