Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oblique plane microscopy faces challenges in achieving fast and aberration-free volumetric imaging due to defocus and spherical aberrations, which are interdependent and require precise knowledge of refractive indices and imaging depth, making conventional correction methods time-consuming and unreliable.
Innovation Solution
An oblique plane microscope with an adjustable telescope system and control unit that evaluates image quality to adjust optical zoom and correction means independently of refractive index measurement, correcting both defocus and spherical aberrations by dividing the image into regions and optimizing magnification and correction based on image quality metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adjustable optical correction means are used to correct spherical aberrations, then image quality is improved, but the focal plane position shifts and requires precise knowledge of refractive indices and imaging depth for proper adjustment
Solution Approach 1:
The system uses image quality assessment to automatically adjust the optical correction means and optical zoom system. The control unit evaluates the image quality and independently adjusts the correction means without requiring manual intervention or precise prior knowledge of refractive indices, creating a closed-loop feedback system that adapts to actual imaging conditions.
Solution Approach 2:
The system performs self-adjustment by automatically evaluating its own image quality and correcting aberrations without external intervention. The control unit monitors image quality metrics and autonomously adjusts the optical correction means and zoom system to optimize imaging parameters based on actual performance.
2Manufacturing precision
If the magnification of the optical zoom system is adjusted to correct defocus aberrations, then imaging accuracy is improved, but the adjustment requires knowledge of refractive indices on both object and image sides
Solution Approach 1:
The system uses image quality assessment to automatically adjust the optical correction means and optical zoom system. The control unit evaluates the image quality and independently adjusts the correction means without requiring manual intervention or precise prior knowledge of refractive indices, creating a closed-loop feedback system that adapts to actual imaging conditions.
Solution Approach 2:
The patent replaces manual measurement and calculation methods with automated image-based detection. Instead of requiring physical measurement of refractive indices, the system uses image quality metrics (sharpness, contrast, etc.) as substitutes to infer optical parameters and automatically adjust the system accordingly.
3Manufacturing precision
If conventional correction methods are used, then aberration correction is achieved, but the process is time-consuming and unreliable due to interdependence of defocus and spherical aberrations
Solution Approach 1:
The system performs preliminary assessment of image quality characteristics to determine the type and severity of aberrations before final adjustment. By evaluating image quality metrics in advance, the control unit can pre-calculate optimal correction parameters and execute adjustments more efficiently, reducing overall correction time.
Solution Approach 2:
The system uses image quality assessment to automatically adjust the optical correction means and optical zoom system. The control unit evaluates the image quality and independently adjusts the correction means without requiring manual intervention or precise prior knowledge of refractive indices, creating a closed-loop feedback system that adapts to actual imaging conditions.
