“We will have years before this technology is put to practical use in everyday use.” “There is no real hologram available or affordable to non-lab consumers,” Nussbaum added. “Holographic displays have been studied for decades, but this technology is not yet ready for commercial use.”ĭavid Nussbaum, CEO of Proto, who works on holographic technology, said that devices that have recently used the term “hologram” are not really holograms. “Today, there really isn’t a solution,” Timothy Wilkinson, a professor of photonics engineering at the University of Cambridge, who studies holograms, told Lifewire by email. Holograms have spent decades in science fiction before becoming a real device available for purchase. “Outside the lab, there are no real holograms that are fully prepared or affordable for consumers.” Call a friend with a hologram “In the context of VR / AR displays, it also offers the unique benefits of being light efficient, providing users with more natural 3D images, and improving the perceptual realism and visual comfort of these immersive experiences.” He added. For example, you can see realistic 3D images without wearing additional 3D glasses. Holographic displays offer unique features, according to Wetzstein. “The results of our research form the basis for future development of miniaturized holographic camera sensor modules.” “The ultimate miniaturization of holographic systems requires research into the miniaturization and integration of individual elements,” said Do Kyung Hwang, one of the authors of the paper, in a press release. Researchers have developed a new type of photodiode by stacking special semiconductors.

However, old polarization detection cameras were too bulky to fit in portable electronics. Polarization in the image sensor can be used to turn a regular camera into a camera that can store 3D holograms. Photodiodes convert light into electrical signals and process the pixels of image sensors in digital cameras and smartphones. This technique has the potential to create small holographic image sensors for 3D digital holograms.
Scientists and collaborators at the Korea Institute of Science and Technology claim to have developed a photodiode that detects the polarization of near-infrared light without an additional polarizing filter. In an email interview, Gordon Wetzstein, a professor at Stanford University who was working on holograms and wasn’t involved in the study, told Lifewire that holograms “can provide 3D capabilities without glasses” to smartphones.
This technique can lead to the long-standing goal of creating holograms without bulky equipment. In a recent article, South Korean researchers claim to have created a new optical sensor that creates 3D images in the camera. Smartphones may soon be able to display holograms.
