Summary of the clip:
How do you achieve a full-color gamut across multiple depth planes using multi-wavelength laser sources?
Creating a true full-color, volumetric 3D display requires a sophisticated combinatorics of light sources. Instead of relying on a simple three-color laser projector, the proposed architecture combines multiple discrete wavelengths per primary color channel. For example, a single primary color image plane is generated using a combination of approximately ten slightly offset laser wavelengths.
By multiplexing these wavelengths across red, green, and blue color channels, the display system can construct a continuous color gamut across all physical depth planes simultaneously. This multi-wavelength matrix projection enables a dense volumetric color space that ensures digital elements remain vibrant, color-accurate, and optically convincing at both near-eye and far-field distances.
Because the system projects all depth planes concurrently without temporal multiplexing, it eliminates the need for high-speed eye-tracking hardware or active eyewear. The physical resolution of each depth plane is limited only by the scan projection system, resulting in a naturally blended, high-fidelity augmented reality experience.
In this short video, you can learn:
* The architectural design of a volumetric display using multiple discrete laser wavelengths per primary color channel.
* How a full-color gamut is maintained across multiple physical focal planes simultaneously.
* The system-level benefits of passive multi-plane projection, including the elimination of eye-tracking requirements.
๐ **Clip Abstract** This clip explains how to generate full-color volumetric images by combining dozens of discrete laser wavelengths across different primary color channels. It showcases how this multiplexing method maintains color gamut fidelity across all depth planes without requiring active eye-tracking or dynamic mechanical optics.

Can true 3D visuals be achieved without triggering the vergence-accommodation conflict?
Can true 3D visuals be achieved without triggering the vergence-accommodation conflict?
Human vision relies on several depth cues working in tandem, including binocular disparity, convergence, accommodation, and motion parallax. Traditional stereoscopic and multi-view 3D displays primarily exploit binocular disparity, which decouples eye convergence from focal accommodation. This mismatch creates the infamous vergence-accommodation conflict (VAC), leading to rapid eye strain, visual fatigue, and nausea during extended use.
To solve this, advanced display architectures must naturally address all human depth cues simultaneously. While technologies like holography and varifocal systems attempt to mitigate these visual discrepancies, they introduce complex computing or mechanical requirements. True multifocal imaging stands out as the most promising pathway to recreate natural focus cues and seamlessly eliminate the vergence-accommodation conflict.
By projecting virtual elements to discrete physical depths, displays can harmonize the eyes' focusing and converging reflexes. This architectural alignment ensures that digital overlays integrate natively into the viewerโs real-world environment, laying the groundwork for comfortable, long-term augmented reality interaction.
In this short video, you can learn:
* The primary depth cues used by the human visual system to perceive authentic 3D spaces.
* Why traditional stereoscopic and multi-view displays trigger the vergence-accommodation conflict.
* The physical advantages of choosing multifocal display architectures over competing 3D display systems.
๐ **Clip Abstract** This clip details how human depth perception cues are addressed by various 3D display technologies. It outlines the visual fatigue issues stemming from the vergence-accommodation conflict in stereoscopic systems and explains why multifocal architectures are uniquely suited to solve them.

Can we exploit chromatic aberration to physically project images onto different depth planes?
Can we exploit chromatic aberration to physically project images onto different depth planes?
Mirage Hyperchromatica introduces an optical architecture that intentionally leverages chromatic dispersion to separate light of different wavelengths into distinct spatial focal planes. By combining multi-wavelength laser sources with high-dispersion, hyperchromatic optics or diffractive optical elements (DOEs), the system can project different wavelength components to physically distinct distances in front of the viewer.
This design flips a traditional optical defectโchromatic aberrationโinto a core functional asset. Because different wavelengths experience different refractive indices and focal lengths, a single optical path can position various colored virtual objects at precise distances in real physical space, without needing moving mechanical parts or complex liquid lens systems.
Experimental setups validate that this physical wavelength separation operates beyond standard RGB primaries. Even within a narrow spectrum, such as separating red lasers of 630 nm and 690 nm, the system can split monochrome virtual objects by several meters in real space, demonstrating a highly versatile and passive method for spatial depth generation.
In this short video, you can learn:
* How to intentionally exploit optical dispersion and chromatic aberration to project light onto separate physical depth planes.
* The role of high-dispersion hyperchromatic optics and diffractive optical elements in passive depth generation.
* Empirical proof showing how minor sub-spectral wavelength variations (e.g., 630 nm vs. 690 nm) translate into physical meters of depth.
๐ **Clip Abstract** This clip introduces a novel optical method that utilizes high-dispersion, hyperchromatic optics to passively project virtual images at varying physical depths. By separating light based on precise laser wavelengths, the system bypasses mechanical focus-tunable lenses to project distinct spatial planes.
