Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current microscope platforms face challenges in achieving high-resolution polarimetric imaging over large areas due to lens aberrations and limitations in designing single microscope objective lenses, making it difficult to observe microscopic-type imaging over wide fields-of-view without mechanical scanning, which is time-consuming and prone to instability.
Innovation Solution
A polarimetric micro-camera array microscope (PCAM) system utilizing a tightly packed array of micro-cameras with different polarizers to capture high-resolution images over large areas by controlling polarization states of incoming light and image capture, allowing for rapid polarimetric measurements and image reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single microscope objective lens is used, then the system structure is simple, but the field-of-view is limited and mechanical scanning is required
Solution Approach 1:
The patent divides a single microscope objective lens into multiple small microscope objective lenses arranged in an array. Each lens captures a portion of the field-of-view, and the images are stitched together to form a complete large-area image. This segmentation allows the system to achieve a wide field-of-view without requiring mechanical scanning, while maintaining relatively simple individual lens designs.
2Area of stationary object
If mechanical scanning is used to observe large areas, then the field-of-view is covered completely, but the imaging process is time-consuming and prone to instability
Solution Approach 1:
The patent uses an array of multiple small microscope objective lenses that simultaneously capture different regions of the sample. This parallel acquisition eliminates the need for sequential mechanical scanning, dramatically reducing imaging time. The segmented lens array captures the entire observable area in a single snapshot, achieving both complete coverage and speed.
Solution Approach 2:
The patent replaces the mechanical scanning system with a static lens array configuration. Instead of moving the objective lens or sample stage mechanically, the system uses multiple fixed lenses positioned at different locations to capture the entire field-of-view simultaneously. This substitution eliminates mechanical instability and time delays associated with scanning.
3Loss of information
If polarization measurements are performed with multiple analyzers, then the polarimetric information is complete, but the number of measurements increases
Solution Approach 1:
The patent combines multiple polarization measurement functions into a single snapshot by using a lens array where each lens is equipped with a specific analyzer orientation. The array simultaneously captures images with different polarization states in parallel, merging what would traditionally require multiple sequential measurements into a single simultaneous acquisition. This approach preserves complete polarimetric information while dramatically improving measurement efficiency.
