Engineering Contradiction Analysis
1Measurement precision
If aberration correction is performed during optical calculation and focus adjustment with actuators, then spectral resolution is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces mechanical actuators and optical adjustment mechanisms with a software-based correction function applied to captured spectra. Instead of using mechanical means to correct aberrations during assembly, the system captures spectra with standard optics and applies computational correction algorithms to achieve high spectral resolution, thereby eliminating complex mechanical adjustment systems.
2Measurement precision
If mechanical actuators are used for focus adjustment, then spectral resolution is improved, but manufacturing cost and production time increase
Solution Approach 1:
The patent eliminates mechanical actuators and focus adjustment mechanisms by using software-based spectral correction. This allows spectrometers to be manufactured using standard optical components without requiring time-consuming manual adjustment processes, enabling mass production while maintaining high spectral resolution through computational correction applied during data processing.
3Measurement precision
If narrow tolerances are applied to optical components, then spectral resolution is improved, but manufacturing cost and production complexity increase
Solution Approach 1:
The patent uses software-based spectral correction to compensate for optical aberrations caused by standard-tolerance components. Instead of requiring precisely manufactured optics with narrow tolerances, the system captures spectra with conventional optical components and applies computational correction algorithms to achieve high spectral resolution, thereby allowing mass production with standard manufacturing capabilities.
4Measurement precision
If space for actuators is allocated, then spectral resolution is improved, but device size increases, preventing miniaturization
Solution Approach 1:
The patent replaces mechanical actuators required for focus adjustment with a software-based correction approach. This eliminates the need for additional mechanical components and adjustment mechanisms, allowing the spectrometer to be miniaturized while maintaining high spectral resolution through computational correction applied to captured spectra.
