It is learned that a patent application from NVIDIA (NVDA.US) was publicly exposed recently. The patent number is US20250004275A1, which is called “Backlight-free Augmented Reality Using Digital Holographic Technology”.
New AR glasses patent exposed
It is said that NVIDIA’s patent is expected to bring many aspects of AR changes. On the one hand, it uses digital holography and ambient light interference principles, and through clever design, AR glasses can achieve excellent display effects in bright outdoor environments, effectively overcoming outdoor display problems.
On the other hand, the key technologies it covers are very eye-catching, such as self-interference holography for intelligent light interference, which can accurately control light; neural network control system based on deep learning model, providing users with a coherent and clear visual experience; and dual-viewpoint stereoscopic display technology, which can create an immersive experience for users.
Nvidia emphasized that it abandoned the traditional backlight system and adopted digital holography and ambient light interference technology. Among them, self-interference holography technology is the technical core of the patent, which fundamentally solves the problem of poor display effect of AR glasses in strong light environment.
This is not the first time that Nvidia has revealed this technology. In June 2024, the results of the cooperation with Stanford University were disclosed, using AI-driven holographic algorithms to optimize the display effect of holographic AR glasses. The team launched holographic glasses with a thickness of only 2.5 mm, using waveguides, holographic near-eye displays and geometric phase lenses to create holographic AR glasses with extremely small thickness.
Holographic technology opens up a new vision of science and technology
In fact, holography was invented by Dennis Gaber in 1947. This technology uses the coherence of light to record all the information of an object. It is a cutting-edge concept involving multiple fields such as optics, physics and information technology. Simply put, holography refers to a technology and phenomenon that can record and reproduce all the information of an object.
In traditional image recording and display methods, usually only partial information of an object can be obtained. For example, photos can only record the light intensity distribution on the surface of an object, but cannot record information such as the phase of light. Holographic technology is different. It can record the amplitude and phase of light at the same time, thereby realizing three-dimensional, all-round recording and reproduction of objects.
WiMi has a strong momentum of development
Today, holographic technology has a wide range of and important applications in the field of science and technology. Public information shows that WiMi Hologram Cloud Inc. (NASDAQ: WIMI), the first holographic AR stock, regards holographic technology as the core driving force for future development. Its investment in holographic technology cannot be underestimated. It optimizes the management of the industrial chain through 5G+holographic+AR technology, improves the quality and interactivity of virtual content, and enhances the immersive experience of the majority of users.
Holographic technology has greatly enriched the entertainment experience of the majority of users. WiMi has brought 5G+holographic+AR technology into the consumer field, and provided a new way to create clearer and richer holograms, which has opened up new possibilities for the practical application of this technology.
For example, through 5G+holographic+AR technology, a holographic phantom stage can be created, allowing real people and virtual people to perform on the same stage, giving the audience a completely three-dimensional feeling. In the future, it may also be possible to achieve multi-person interaction, create an immersive virtual environment, and take the holographic technology entertainment experience to a higher level.
Ending
In fact, with the development of virtual reality and augmented reality technology, holographic technology will also be combined with these technologies to bring users a more realistic virtual experience. At the same time, the popularization of holographic technology will also drive the development of related industrial chains, such as optical components, projection equipment and software. Therefore, with the continuous advancement of science and technology, holographic technology has shown great potential in various fields. I believe that in the future, holographic technology will also play an important role in more fields and bring more convenience and innovation to everyone’s life.
