Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional optical image capturing systems for portable electronic devices face challenges in achieving high imaging quality with increased pixel count, large aperture, and wide view angle due to aberration and distortion issues, making it difficult to meet the requirements for advanced camera functionalities like micro filming and night vision.
Innovation Solution
The optical image capturing system employs a combination of six-piece optical lenses with specific refractive powers and surface geometries to enhance light intake and view angle, incorporating inflection points on lens surfaces for aberration correction and improved imaging quality, while maintaining miniaturization and manufacturing feasibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a large aperture design is used to increase light intake, then imaging quality for night view is improved, but optical aberration increases resulting in deterioration of peripheral image formation quality
Solution Approach 1:
The optical system is divided into six separate lens elements (first lens element, second lens element, third lens element, fourth lens element, fifth lens element, and sixth lens element) arranged in sequence. Each lens element is designed with specific refractive powers and surface curvatures to collectively achieve the desired aperture while controlling aberrations. This segmentation allows the system to manage optical paths and correct aberrations more effectively than a single lens could.
Solution Approach 2:
Different lens elements are assigned different refractive powers and surface characteristics tailored to their specific positions and functions in the optical path. The first lens element has a different refractive power than the second, and so on. Each lens is optimized locally to contribute to overall aberration correction while maintaining the large aperture design for improved light intake.
