Hologram Recording Medium Multi-View Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for manufacturing hologram recording media that allow different original images to be reproduced when observed from different positions suffer from reduced resolution due to the need to record each image on separate regions, resulting in a resolution that is one-third of the original.
Innovation Solution
A method and device that compute and form interference fringe patterns on a physical medium by considering only light components reaching specific observation regions, allowing for high-resolution reproduction of multiple images by synthesizing object light components from multiple unit light sources and using a three-dimensional coordinate system to set recording planes and observation regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple original images are recorded on separate regions of the hologram recording surface, then different images can be reproduced from different positions, but the resolution of reproduced images is reduced to one-third of the original
Solution Approach 1:
The hologram recording surface is divided into multiple regions, with each region dedicated to recording a specific original image. By partitioning the recording surface into distinct segments (first region for first original image, second region for second original image, etc.), the system enables different images to be reproduced from different positions while maintaining optimal resolution for each image within its designated region
Solution Approach 2:
Each region of the hologram recording surface is optimized specifically for recording its associated original image, allowing the recording conditions and parameters to be locally tailored. This ensures that each original image achieves high resolution in its dedicated region without being compromised by the presence of other images, thereby maintaining manufacturing precision while enabling multi-image reproduction

AI summary
A method and a device for manufacturing a hologram recording medium that has an arrangement by which different original images are reproduced when observed from different positions. The method includes preparing a plurality of original images, setting a predetermined recording plane, setting a predetermined reference light, setting a plurality of observation regions, computing an interference fringe pattern, and forming the interference fringe pattern on a physical medium. When computing an interference fringe pattern, computations of only the light components of each original image which would reach the respective observation region are performed.
