Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If image sensors with different optical distances are used to improve light sensing capability, then light sensing performance is improved, but chromatic aberration occurs during image restoration
Solution Approach 1:
The incident light is segmented into multiple waveband lights (first waveband light, second waveband light, third waveband light) corresponding to different color channels. Each waveband light is directed to a dedicated light sensing assembly, allowing independent optimization of optical paths for each color channel while maintaining equal optical path lengths to prevent chromatic aberration.
Solution Approach 2:
The patent ensures that all light sensing assemblies are positioned at equal optical path lengths from the light splitting assembly. This equipotential optical path design ensures that light rays of different wavebands travel equal distances, eliminating optical path difference-induced chromatic aberration while maintaining high light sensing performance.
2Manufacturing precision
If optical path lengths of different waveband lights are made equal to prevent chromatic aberration, then image quality is improved, but optical system complexity increases
Solution Approach 1:
A light splitting assembly is introduced as an intermediary component between the incident light and multiple light sensing assemblies. This mediator efficiently divides the incident light into different wavebands and directs them along separate optical paths, simplifying the overall system architecture while ensuring equal optical path lengths for each waveband.
Solution Approach 2:
Multiple light sensing assemblies with different spectral sensitivities are merged into a single integrated system, with each assembly dedicated to sensing a specific waveband. This combining approach allows simultaneous capture of multiple color channels with optimized optical paths, achieving high image quality without excessive system complexity.
