Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser imaging systems using beam splitters suffer from beam loss and illumination support issues, which hinder precise targeting and beam orientation in target processing systems.
Innovation Solution
A reflection system with a mirror having a non-reflective or weakly reflective zone for the emission end of optical fibers, allowing the same optics to transmit and image the treatment beam, and incorporating a method for manufacturing this mirror with a reflective surface and optical fibers, along with optional diffraction gratings and lenses for focusing and beam control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a beam splitter is used to transmit the treatment beam and reflect imaging light, then imaging functionality is achieved, but beam losses occur and illumination support is compromised
Solution Approach 1:
The mirror surface is segmented into distinct functional zones: a reflective zone for imaging and a non-reflective zone for beam transmission. This segmentation allows the single optical component to handle both imaging and beam transmission without the losses associated with beam splitters.
Solution Approach 2:
The mirror serves multiple functions simultaneously: it reflects imaging light back to the camera for target visualization, transmits the treatment laser beam to the target, and provides structural support for the optical fiber. This multi-functionality eliminates the need for separate beam splitter and support structures.
2Measurement precision
If a beam splitter is used for imaging, then target visualization is achieved, but the system becomes complex and less reliable
Solution Approach 1:
The mirror combines multiple functions into a single component: beam transmission, imaging reflection, and optical fiber support. This merging reduces the number of separate components needed in the system, simplifying the overall device architecture and improving reliability.
Solution Approach 2:
The mirror is designed as a universal optical element that performs both beam transmission and imaging reflection, replacing the need for separate beam splitters and support structures, thereby reducing system complexity.
3Device complexity
If the same optics are used for both beam transmission and imaging, then system complexity is reduced, but precise beam orientation control becomes challenging
Solution Approach 1:
Different zones of the mirror have different optical properties: the reflective zone maintains high reflectivity for imaging, while the non-reflective zone allows beam transmission. This local differentiation enables precise beam orientation control through the non-reflective zone while maintaining imaging capability through the reflective zone.
