In the science fiction novel "The Three-Body Problem," the scene of "the universe flashing for you" has now become a reality. Recently, a 3D display technology called EyeReal successfully appeared in the prestigious academic journal Nature, attracting widespread attention from the tech community. The lead author of this technology is a 26-year-old Ph.D. student from Fudan University, who co-developed this revolutionary display with the Shanghai Artificial Intelligence Laboratory and the Shanghai Innovation Institute.

The biggest highlight of EyeReal technology is that it can precisely project 3D images into the viewer's field of vision without the need for glasses. Unlike traditional 3D display technologies, EyeReal offers a viewing angle exceeding 100 degrees. No matter how the viewer moves, the image remains smooth and clear, eliminating the blur or ghosting issues seen in previous devices.

In terms of size, EyeReal is comparable to a regular 24-inch desktop monitor, but its effective 3D imaging area reaches 0.1 to 0.2 square meters, which is 1000 times larger than the previous holographic technology that could only show an area as small as a fingernail. In addition, EyeReal supports true "full parallax" display, presenting stereoscopic effects in three dimensions: horizontal, vertical, and radial. This design ensures that the geometric perspective changes of objects are consistent with the real world when viewed from different angles.

Even more amazing is that EyeReal introduces "focus parallax" technology, naturally simulating the depth of field effect of the human eye. When viewers focus on foreground objects, the background becomes naturally blurred, and vice versa. This design effectively eliminates the dizziness caused by watching, ensuring comfort even during long viewing sessions.

Behind the technology, EyeReal combines computational optics and artificial intelligence, utilizing a new strategy based on dynamic space-bandwidth product (SBP) to break through physical limitations. It locks onto the viewer's eye position in real time, accurately projecting light to form continuous 3D images. This complex system is built on multi-layer liquid crystal panels and advanced AI algorithms, offering users an unprecedented visual experience.

With ongoing technological advancements, EyeReal has the potential to bring revolutionary changes in fields such as virtual reality, gaming, and medicine, and we look forward to it.
