Amplitude-Modulated Hologram Encoding for Real-Time 3D Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display technologies face challenges in real-time image processing and optical reconstruction due to the high amount of information required for generating 360-degree holographic content, leading to passive content observation and bulky systems, making it difficult to implement in mobile or wearable holographic terminals.
Innovation Solution
The method involves encoding hologram information using a real number hologram function derived from the hologram information, determining an intermediate hologram function based on the sign characteristic, and encoding it for a modified amplitude-only (MAO) holographic terminal system, allowing for the production and evaluation of high-quality 3D hologram content and image quality measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 360-degree holographic image content is generated based on various real objects or computer graphics, then the holographic display achieves perfect parallax and depth representation, but the information amount increases significantly making real-time image processing and optical reconstruction difficult
Solution Approach 1:
The patent extracts only the real number part from the complex hologram information, discarding the imaginary part. This extraction reduces the information amount by approximately half while maintaining the essential holographic reconstruction capability, enabling real-time processing without sacrificing fundamental image quality
Solution Approach 2:
The patent uses only a portion of the complete complex hologram information (specifically the real number part) rather than processing the full information set. This partial action approach achieves acceptable holographic reconstruction with significantly reduced computational burden, trading off some theoretical perfection for practical real-time performance
2Adaptability or versatility
If new 360-degree image content for holography is generated, then the holographic display can provide immersive 3D content, but the system volume becomes great due to complex optical systems requiring configuration on an optical table
Solution Approach 1:
The patent removes the complex optical requirements by extracting only the essential real number component of hologram information. This simplification allows holographic content to be generated and displayed using simpler, more compact optical systems that can be integrated into mobile and wearable devices rather than requiring large optical table configurations
Solution Approach 2:
The patent changes the fundamental parameter of hologram representation from complex numbers to real numbers only. This parameter change fundamentally alters the system requirements, enabling the same holographic functionality to be achieved with reduced optical complexity and smaller system volume suitable for portable applications
3Productivity
If existing images are reconstructed rather than generating new 360-degree image content, then the processing burden is reduced, but the viewer can only passively observe content without real-time interaction
Solution Approach 1:
The patent enables real-time hologram encoding by processing only the real number part of the input data rather than complete complex information. This partial processing approach provides sufficient quality for interactive applications, transforming the system from passive reconstruction to active real-time content generation capable of responding to user interactions
