“For example, we may start seeing limited use of holograms to produce things like keypads and even holographic menus,” said Won. This is because making holograms an everyday sight will require the development of not just holographic displays but also holographic content, holographic filming devices, and processes for transmitting the vast amounts of data that holograms will generate.Īs Won pointed out, however, there are ways that holograms could start popping up in our daily lives sooner rather than later. While the thought of holograms becoming a part of daily life is no doubt exciting, the researchers stressed that the technology still has a long way to go before it resembles the holograms we’ve seen in science fiction films. “From creation to reproduction of holograms, a complete system was implemented to secure the possibility of commercialization,” said Lee. These advancements, Lee explained, could help pave the way for holograms to find their way into more aspects of everyday life. The new method utilizes what’s known as a ‘layer-based’ calculation, while most methods employ a process known as ‘point cloud-based’ calculation.Ĭalculating holograms in real time using FPGA, the new method optimizes an algorithm by applying conditions that prevent information loss and excessive sampling. Another notable achievement of the study is that it identified a method for generating 4K holographic images in real time that utilizes a single-chip field-programmable gate array (FPGA) 3 for hologram calculation. In the process of overcoming the narrow viewing angle issue, the team created a new kind of holographic display that features a thin, flat-panel design just like those seen in the market today. However, you can expand the viewing angle roughly 30-fold by bending the image toward the viewer using S-BLU.” A conventional 4K screen 10 inches in size offers a very small viewing angle of 0.6°. As Kanghee Won explained, “An S-BLU consists of a thin, panel-shaped light source called a coherent-backlight unit (C-BLU), which transforms an incident beam into a collimated beam, and a beam deflector, which can adjust the incident beam to a desired angle. In order to solve the issue of narrow viewing angles, SAIT’s holographic display research team developed a special optical element called a steering-backlight unit (S-BLU). It perfectly replicates objects with light, producing images that look as lifelike as the real thing.” “While most 3D display methods provide only some of these cues, a hologram provides them all. “The human eye utilizes various depth perception cues, including binocular parallax, two pupil angles, focus adjustment and motion parallax, 2 to recognize the depth of an object,” said An. As Hong-Seok Lee explained, “While a conventional display depicts images based on light intensity, holograms control not just the intensity of light but also its phase to produce images that appear three-dimensional.”Īccording to Jungkwuen An, a key reason why holographic displays are seen as the most ideal form of 3D display comes down to how human beings perceive depth. The key difference between them boils down to the dimension at which the images are presented. In terms of their ability to produce realistic images, they’re similar to the high-resolution displays that we see throughout our daily lives. In a nutshell, holograms create images of objects that don’t actually exist. What does SAIT’s thesis mean for the study and development of holograms, and how could holograms eventually be applied to our daily lives? To answer those questions and more, Samsung Newsroom interviewed Master Hong-Seok Lee of the Samsung Advanced Institute of Technology, along with Principal Researcher Jungkwuen An and Staff Researcher Kanghee Won. 1 After eight years of trials, the team published a thesis on slim-panel holographic video displays in the world-renowned scientific journal, Nature Communications.
