Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Near-eye light field displays face a significant reduction in image resolution, which affects the quality of both two-dimensional and three-dimensional information displayed, making it difficult to provide a realistic and comfortable visual experience for users.
Innovation Solution
An optical element comprising a first birefringent layer, a second birefringent layer, and a gas layer, where the gas layer is inclined relative to the optical element, generates two sub-image beams with different deflection angles, which are offset to create a high-resolution image when combined through persistence of vision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If near-eye light field displays use a light field imaging mechanism to reduce optical path length, then the overall device becomes lightweight and slim, but image resolution drastically reduces
Solution Approach 1:
The invention divides the image beam into multiple sub-image beams (first sub-image beam and second sub-image beam) with different deflection angles through the inclined gas layer. Each sub-image beam carries partial image information, and their superposition reconstructs a high-resolution image, effectively segmenting the imaging function to overcome resolution limitations
Solution Approach 2:
The gas layer is disposed at an inclination angle relative to the optical element, introducing a spatial dimension transformation. This inclination causes the image beam to split into sub-beams with different deflection angles in the lateral direction, adding spatial diversity to the imaging process and enabling resolution enhancement without increasing optical path length
2Adaptability or versatility
If near-eye light field displays provide both two-dimensional and three-dimensional image information, then visual realism improves, but image resolution drastically reduces
Solution Approach 1:
The invention segments the single image beam into multiple sub-image beams with different deflection angles, where each sub-beam carries encoded spatial information. The superposition of these segmented beams reconstructs both 2D and 3D information at higher resolution, allowing the system to maintain versatile visual information capability while improving resolution
Solution Approach 2:
The invention merges multiple sub-image beams with different deflection angles through superposition to reconstruct the final image. This combining process integrates the spatial information from each sub-beam, enabling simultaneous display of 2D and 3D visual information with enhanced resolution

AI summary
An optical element configured to allow an image beam passing through is provided. The optical element includes a first and a second birefringent layer and a gas layer between the first and the second birefringent layer. An extension direction of the gas layer is inclined with respect to an extension direction of the optical element, wherein the image beam passes through the first birefringent layer, the gas layer and the second birefringent layer in sequence. A first and a second sub image beam having different deflection angles are generated from the image beam when the image beam enters the gas layer. After the first and the second sub image beam are emitted from the second birefringent layer, a transmission path of the first and the second sub image beam are offset from each other by an offset distance, thereby improving resolution of an image to be viewed.
