Modular Projection Lens Fourier Aperture Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection systems lack modularity, making it difficult to access and adjust the Fourier aperture, which is essential for adapting to various theater settings and achieving optimal contrast and resolution, as the Fourier plane is often embedded within the lens assembly and not easily accessible.
Innovation Solution
A modular projection lens system comprising a Fourier lens assembly with a removable attachment section and a zoom lens assembly, allowing for the placement of an aperture at the Fourier transform plane to block incident light, enabling easy access and adjustment of the Fourier aperture for different theater configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the Fourier aperture is embedded within the lens assembly, then the structural integrity is maintained, but the accessibility for adjustment is reduced
Solution Approach 1:
The lens assembly is divided into separate modular components: a Fourier lens assembly and a zoom lens assembly. The Fourier aperture is integrated into the Fourier lens assembly, which can be independently removed and replaced. This segmentation allows easy access to the Fourier aperture for adjustment while maintaining the overall structural integrity of the complete lens system when assembled.
2Adaptability or versatility
If the entire projection zoom lens system is replaced to adapt to different theater settings, then the optimal contrast and resolution are achieved, but the cost and time increase
Solution Approach 1:
The lens system is segmented into modular assemblies that can be independently configured. The Fourier lens assembly with its aperture can be quickly swapped between different zoom lens assemblies to adapt to various theater settings, eliminating the need to replace the entire projection zoom lens system while maintaining optimal contrast and resolution performance.
Solution Approach 2:
The Fourier lens assembly is designed as a universal component that can be attached to different zoom lens assemblies. This multi-functionality allows a single Fourier lens assembly to work with multiple zoom lens configurations, enabling adaptation to diverse theater settings without requiring multiple complete lens systems.
