The patent application introduces a volumetric display system that generates holographic images within an ambient air display volume using a columnar laminar flow generation system. This system combines ambient atmosphere air flow with particulate flow to create parallel streams of laminar air and particulates. A laser projection system then aligns beams to overlap these particulate streams, illuminating them to form the desired holographic image. This approach enables the creation of mid-air volumetric displays without the need for screens or containment devices.
The technology addresses limitations of conventional holographic displays, which often rely on illusions, reflections, or physical light arrays and typically require screens or containers. These traditional methods often have restricted viewing angles and limited interactivity. The disclosed system aims to provide a scalable, interactive display that can present digital visual information seamlessly in real-world spaces without such constraints. It offers advantages like scalability, safety, and cost-effectiveness compared to existing technologies.
The disclosure outlines various embodiments of the holographic display system, emphasizing its ability to present mid-air, volumetric content interactively. Key components include a base unit for generating laminar flows, an atmosphere receive unit, and a laser beam projection system. The system is designed for flexibility in scale and can be used indoors or outdoors under various lighting conditions. Additionally, it includes features such as an interactive spatial sensor module and an integrated audio system to enhance user interaction with the displayed holograms.
The technology offers several novel capabilities not present in current systems. It allows for viewing from any angle around the display, supports real-time content updates, and can be scaled from small to large installations. Unlike other systems, it does not rely on screens or meshes for reflection and provides true volumetric content that appears to float and change mid-air. The system's interactivity is enhanced by allowing touch interactions from multiple directions, making it suitable for diverse applications like entertainment and training.
Referred to as the Voxel-Atmosphere Stabilization Terminal (VAST) System, this setup comprises several units: a top unit with audio speakers, a base unit with content control and interaction modules, a right unit housing the laser projector, and a left unit for laser termination. These components can be interconnected or operate wirelessly depending on installation needs. The VAST system provides a comprehensive mid-air volumetric display solution capable of delivering visible 3D voxels with coordinated spatial audio and touch reactivity.
