Using physics simulations for computer-generated holography involves calculating the appearance of many chunks of a hologram and then combining them to get the final hologram, Shi notes. “Everything worked out magically, which really exceeded all of our expectations,” says study lead author Liang Shi, a computer scientist at MIT. They detailed their findings this week, which were funded in part by Sony, online in the journal Nature. Now researchers at MIT have developed a new way to produce holograms nearly instantly-a deep-learning based method so efficient, it can generate holograms on a laptop in a blink of an eye. However, these often come at the cost of image quality. In order to bring holographic video to the masses, scientists have tried a number of different strategies to cut down the amount of computation needed - for example, replacing complex physics simulations with simple lookup tables. As such, generating holographic video has often required a supercomputer’s worth of computing power. However, although companies such as Samsung have recently made strides toward developing hardware that can display holographic video, it remains a major challenge actually generating the holographic data for such devices to display.Įach hologram encodes an extraordinary amount of data in order to create the illusion of depth throughout an image. Holographic video displays create 3D images that people can view without feeling eye strain, unlike conventional 3D displays that produce the illusion of depth using 2D images. The pixels of each hologram scatter light waves falling onto them, making these waves interact with each other in ways that generate an illusion of depth. Using artificial intelligence, scientists can now rapidly generate photorealistic color 3D holograms even on a smartphone. And according to a new study, this new technology could find use in virtual reality (VR) and augmented reality (AR) headsets and other applications.Ī hologram is an image that essentially resembles a 2D window looking onto a 3D scene.
