Solution Overview
Problem
Conventional devices for creating light in space often produce visible scanning lines or artifacts, and high-powered light sources can be dangerous and unsightly, failing to provide genuine multi-dimensional images without visible image creation artifacts.
Innovation Solution
A device that generates low-intensity visible spectrum light rays which intersect to create visible images in space, remaining non-visible themselves, allowing for the creation of patterns, colors, and moving images without visible scanning lines or artifacts, using optics and light sources that adjust intensity and frequency to ensure the light is only visible above a certain threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high-powered light sources are used to create visible images in space, then the visibility and brightness of the image is improved, but the safety risk and visibility of scanning lines/artifacts increases
Solution Approach 1:
The patent divides the light source into multiple separate light sources arranged in a specific geometric configuration. Each light source operates at low power individually, but their combined interference patterns create a visible image. This segmentation allows the system to achieve sufficient image brightness through constructive interference without requiring any single light source to operate at high power levels that would create safety hazards or visible scanning artifacts.
Solution Approach 2:
The patent employs periodic modulation of the light sources at frequencies above human visual perception (ultrasonic or ultraviolet frequencies). The light sources are modulated in a coordinated manner to create temporal interference patterns that form stable visible images. This periodic action allows the system to create visible images without continuous high-powered illumination, reducing safety risks while maintaining image visibility through temporal averaging in the human eye.
2Manufacturing precision
If conventional light sources are used to create images in space, then visible images can be formed, but visible scanning lines and artifacts are produced that detract from the image quality
Solution Approach 1:
The patent introduces an optical interference field as an intermediary between the light sources and the final image. Multiple low-powered light sources create interference patterns in the optical field, and this interference field acts as the mediator that forms the visible image without requiring mechanical scanning or visible artifact-generating mechanisms. The interference field itself becomes the image-forming mechanism, eliminating the need for visible scanning lines.
Solution Approach 2:
The patent changes the fundamental parameter of light frequency to ultrasonic or ultraviolet ranges, which are invisible to the human eye. By operating in this frequency range and using interference patterns to create visible images through modulation, the system eliminates visible scanning lines and artifacts while maintaining high image quality. The parameter change from visible light to invisible frequencies is key to eliminating the harmful visual artifacts.
3Illumination intensity
If visible light sources are used for disembodied lighting, then the light can be seen, but the supporting mechanism becomes visible connecting the light source to the mounting surface
Solution Approach 1:
The patent transitions from traditional three-dimensional physical light sources requiring mechanical support to a four-dimensional solution using temporal interference patterns. By utilizing time-varying interference of multiple light sources, the system creates disembodied lighting effects where the image appears to float in space without physical connection. This dimensionality change from spatial to temporal-domain light manipulation eliminates the need for visible supporting mechanisms.

Implementation Method 1
Multiple rays of light which are in the visible spectrum with a low intensity such that the light is not visible by a normal observer intersect. When the constructive intensity of the intersecting light is above the threshold for being visible then light appears.
Implementation Method 2
The reflected light on the wall is usually brighter than the light reflected along the beam by the particles.

AI summary
A device that creates visible light in space comprises of a light source and optics system that result in irradiated visible spectrum light rays with a low intensity such that the light is not visible by the normal observer. Multiple rays of visible-spectrum low-intensity non-visible light intersect. When the constructive intensity of the intersecting light is above the threshold for being visible then light appears at that place. The light rays to and from the visible light remain non-visible. The addition of irradiated visible light results in additional visual effects. The visible light can be moved in space, and form multi-dimensional images and holograms. User and programmable controls, with communication abilities and data storage, can mediate the light source and optics to control the visible image.
