Conventional integral imaging uses a fine fly‐eye lens whose elemental lens is perceived as one pixel. Coarse integral imaging uses a coarse fly‐eye lens so that multiple pixels are observed through each elemental lens, which generates a real image or a virtual image of the display panel. By using interleaved Fresnel lenses where the width of elemental prisms changes gradually, discontinuity of image due to the coarseness of lens array becomes indistinct. When multiple projection‐type display panels with high transmittance are layered, a layered real image or virtual image without moiré is formed, which enables integral imaging with volumetric features.
Join us as we delve into the captivating realm of glass-free 3D displays with an exclusive interview with Visual Media Lab of the University of Tsukuba. In this video, we meet the talented individual behind the revolutionary technology and witness mind-blowing 3D images without the need for special glasses or goggles.
Engage in an insightful conversation with the experts, unraveling the secrets behind this innovative display technology. Learn how the team achieves the mesmerizing effect by displaying multi-view images on the back screen and utilizing lens arrays and large aperture lenses to distribute them to different angles. This ingenious approach creates multiple viewpoints, allowing viewers to observe the 3D images with binocular parallax and motion parallax.
Explore various types of glass-free 3D displays, including the virtual image type that constructs 3D images far behind the display, and the transmissive display type that generates volumetric imaging, giving a sense of depth and volume to the visuals. The knowledgeable experts discuss the technical aspects and intricacies of these displays, shedding light on their potential applications and limitations.
Discover the number of views available in these displays, with 11 horizontal and six vertical viewpoints, enabling a truly immersive experience. Maria’s curiosity leads to an intriguing discussion about the possibilities of using this technology for huge holographic home displays, and the experts explain the requirements for creating larger displays, including bigger screens, lens arrays, and high brightness levels.
The conversation also touches on overcoming challenges, such as reflections and ambient lighting conditions. The experts share their ongoing efforts to optimize the technology for better image quality and propose potential solutions, including lens array adjustments and specialized coatings.
As the interview progresses, Maria explores the latest research and innovations, including elemental interleaved lenses, which enhance the image quality and transition between views. The team’s future work encompasses creating see-through augmented reality (AR) displays and combining haptic feedback systems to enable virtual touch interaction.
Witness the magic of this remarkable technology as Hatsune Miku, a virtual CG character, comes to life in a box, showcasing the capabilities and potential of glass-free 3D displays. The experts provide insights into the current resolution and express their aspirations for higher resolutions, such as 8K and 16K, to further enhance the visual experience.
