Core Viewpoint - Kyocera Corporation has developed a new meta-lens technology that allows for precise manipulation of focal positions based on light wavelength, leading to the creation of a prototype Wearable Aerial Display that offers compactness and natural depth perception in images, set to debut at CES 2026 [1]. Group 1: Key Features of the Meta-Lens - The meta-lens is an ultra-thin optical component, less than 1mm thick, utilizing a metasurface to control light propagation, significantly reducing the size compared to conventional lenses which are typically over 1cm thick [2]. - By designing meta-atoms precisely, multiple optical functions can be integrated into a single meta-lens, reducing the number of components needed and allowing for smaller and lighter optical systems [3]. Group 2: Image Display Capabilities - The meta-lens can shift focal positions based on light color, enabling images of different colors to appear at varying depths, creating three-dimensional aerial visuals with natural depth perception without bulky optical assemblies [4]. Group 3: Wearable Aerial Display Prototype - The combination of the new meta-lens with existing aerial imaging technologies has resulted in a compact, lightweight wearable display capable of projecting floating images with realistic depth, representing a significant advancement in visual interfaces for body-worn devices [5]. Group 4: Future Potential - Future advancements may enhance wavelength control for full-color, high-resolution aerial images, and improved meta-atom design could enable smooth 3D visuals in mid-air, making meta-lenses suitable for various applications in consumer electronics and industrial equipment [6].
