Solution Overview
Problem
Current technologies in holography and computer-generated holography lack the versatility to accurately recognize complex, sensory-based information, particularly in real-world environments, and fail to differentiate foreground from background effectively, leading to limited recognition capabilities beyond laboratory settings.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional holographic recording techniques are used, then holograms can be recorded and reconstructed, but the system lacks the versatility to accurately recognize complex sensory-based information in real-world environments
Solution Approach 1:
The patent segments the image into multiple spatial cross-sections and further divides each cross-section into spectral components (wavelength bands). This segmentation allows the system to analyze different spatial and spectral characteristics separately, enabling accurate recognition of complex patterns while maintaining versatility across different imaging conditions.
Solution Approach 2:
The patent introduces spectral dimension by recording holograms at multiple wavelength bands and combining them with spatial cross-section information. This multi-dimensional approach (spatial + spectral) transforms the recognition system from two-dimensional spatial analysis to four-dimensional analysis (x, y, wavelength, temporal), dramatically improving differentiation accuracy for complex sensory data.
2Reliability
If traditional holographic methods are applied, then basic hologram reconstruction is achieved, but the system cannot effectively differentiate foreground from background
Solution Approach 1:
The patent segments the holographic recording into multiple wavelength bands and spatial cross-sections, allowing foreground and background to be differentiated through their distinct spectral and spatial signatures. This segmentation enables reliable pattern recognition by analyzing specific wavelength ranges that highlight foreground features while suppressing background interference.
Solution Approach 2:
The patent applies different analysis methods to different spatial cross-sections and wavelength bands based on local characteristics. By tailoring the recognition approach to specific regions and spectral components, the system achieves high reliability in foreground-background differentiation without requiring uniformly complex processing across the entire image.
3Measurement precision
If conventional recognition techniques are used, then simple pattern matching is possible, but the system fails to recognize complex waveforms as distinct objective entities
Solution Approach 1:
The patent segments complex waveforms into multiple spatial cross-sections and spectral components, transforming the recognition task from analyzing entire complex waveforms to comparing segmented features. This segmentation reduces the computational burden while maintaining high differentiation precision by focusing on characteristic spectral and spatial signatures of distinct waveform entities.
Solution Approach 2:
The patent transforms waveform recognition from temporal domain analysis to combined spatial-spectral domain analysis by recording at multiple wavelength bands and spatial cross-sections. This dimensionality change enables precise differentiation of complex waveforms as distinct entities by exploiting their unique spectral-spatial fingerprints, reducing the need for extensive temporal data processing.
