Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electromagnetic wave detection systems face challenges in improving image resolution, particularly in the angle-of-view range away from the main axis, where resolution is lower compared to the main axis neighborhood.
Innovation Solution
The electromagnetic wave detection apparatus incorporates a travel unit with a reference surface of pixels that can switch the direction of incident electromagnetic waves, a second image formation unit, and detectors arranged to satisfy the Scheimpflug principle, allowing for improved image resolution by focusing on the main axis neighborhood of the secondary image formation optical system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional image formation system is used with parallel surfaces, then the structure is simple, but the resolution in the angle-of-view range away from the main axis is lower
Solution Approach 1:
The patent applies the Scheimpflug principle by making the image surface, lens plane, and detector surface intersect along a common axis rather than being parallel. This dimensional rearrangement allows the entire angle-of-view range to be imaged with high resolution on the detector surface, resolving the contradiction between maintaining simple structure and achieving uniform high resolution across all viewing angles.
2Area of stationary object
If the detection surface is positioned to capture the full angle-of-view range, then the coverage area is increased, but the resolution away from the main axis deteriorates
Solution Approach 1:
By arranging the detector surface, lens main surface, and image surface to intersect along a common axis according to the Scheimpflug principle, the patent achieves both full angle-of-view coverage and uniform high resolution across the entire detection area, eliminating the trade-off between coverage area and resolution.
3Device complexity
If the main axis of the second image formation unit is aligned perpendicular to the reference surface, then the optical path is simplified, but the image quality in the angle-of-view range away from the main axis is reduced
Solution Approach 1:
The patent tilts the detector surface and image surface relative to the reference surface so that they intersect along a common axis with the lens main surface. This angular arrangement optimizes the optical path to achieve high image quality across the entire angle-of-view range while maintaining reasonable structural simplicity.
