Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical systems and devices lack the ability to dynamically adjust optical conditions based on specific purposes, such as varying light transmission characteristics, which limits their versatility and efficiency in imaging and projection applications.
Innovation Solution
An optical system featuring a rotational movement member with non-parallel alignment to the optical axis, incorporating light transmissive regions with different characteristics, allowing for dynamic adjustment of light conditions by rotating these regions into the optical path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a rotational movement member with parallel alignment to the optical axis is used, then the structure is simple, but vignetting occurs and the full angle of view cannot be maintained
Solution Approach 1:
The rotational movement member is designed with non-parallel alignment between its rotational axis and the optical axis, creating an asymmetric configuration that prevents vignetting while maintaining structural simplicity. This asymmetric arrangement allows light rays to pass through the light transmissive regions without being blocked, preserving the full angle of view of the objective lens.
2Adaptability or versatility
If multiple light transmissive regions with different characteristics are incorporated, then optical versatility is improved, but device complexity increases
Solution Approach 1:
The rotational movement member integrates multiple light transmissive regions with different light transmission characteristics (such as different wavelengths, polarizations, or intensities) into a single component. By rotating this multi-functional member, the system can dynamically switch between different optical conditions, providing versatility without requiring multiple separate components or complex mechanisms.
Solution Approach 2:
The system employs a rotatable movement member that can dynamically adjust which light transmissive region is positioned in the optical path. This dynamic configuration allows the optical system to adapt to different imaging or projection requirements by simply rotating the member, thereby achieving versatile optical control without permanent structural complexity.
3Object-affected harmful factors
If the rotational axis is non-parallel to the optical axis, then vignetting is prevented and full angle of view is maintained, but manufacturing precision requirements increase
Solution Approach 1:
The design deliberately incorporates non-parallel alignment between the rotational axis and optical axis as an asymmetric feature. This asymmetric configuration is specifically engineered to prevent vignetting by ensuring that light rays from all directions can reach the light transmissive regions without being blocked by the housing or other components, thus maintaining the full angle of view.
