Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current quasi-holographic display technologies fail to provide a true spatial effect, as viewers cannot perceive holographic images from different angles with the same display effect as real scenes, limiting the immersive experience.
Innovation Solution
An image display system comprising holographic image acquiring devices, image synthesis devices, and image reconstruction devices that obtain, synthesize, and reconstruct holographic image information using light sources, optical assemblies, and holographic storage materials to generate and present holographic synthetic images, allowing multiple three-dimensional scenes to be combined into one, enhancing user perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If quasi-holographic display technology using projector and phantom imaging film is used, then spatial effect is achieved, but true holographic perception from multiple angles is not obtained
Solution Approach 1:
The patent uses a camera to capture optical images of the scene and stores these copies in holographic storage material. This copying approach allows the scene to be recorded and replayed from multiple angles, achieving true holographic perception without requiring complex real-time optical paths
Solution Approach 2:
The patent changes the state of light from visible to invisible by using infrared light for illumination and capture, then converts it back to visible light during playback. This parameter change enables the system to achieve authentic holographic display while avoiding the limitations of visible light quasi-holographic methods
2Illumination intensity
If visible light is used for holographic capture, then scene imaging is achieved, but infrared illumination and invisible light capture are not utilized
Solution Approach 1:
The patent employs infrared light sources to illuminate the scene and uses an infrared-sensitive camera to capture the reflected infrared light. This parameter change from visible to infrared wavelength enables illumination with invisible light and capture that can then be converted back to visible for display, achieving versatile light wavelength adaptation
3Quantity of substance
If single scene holographic imaging is performed, then one three-dimensional scene is captured, but multiple three-dimensional scenes cannot be synthesized
Solution Approach 1:
The patent merges multiple optical images captured from different scenes into a single composite holographic image. The image processing device combines the captured images and uses a single spatial light modulator to replay all scenes simultaneously, achieving multi-scene synthesis without requiring multiple complex optical paths
Solution Approach 2:
The patent uses a single holographic storage material and spatial light modulator that can handle multiple scenes universally. This multi-functional component replaces what would otherwise require separate dedicated systems for each scene, reducing overall system complexity while enabling synthesis of multiple three-dimensional scenes
