Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laser spectroscopic diagnosis methods, such as Raman spectroscopy and laser-induced breakdown spectroscopy, face challenges in accurately diagnosing tissues due to variations in results based on the laser radiation position, as the small spot size of the laser beam makes it difficult to consistently identify and target the correct position on the object.
Innovation Solution
A method and device that utilize a guide light to visually indicate the radiation position of a pulsed beam onto a suspicious tissue, allowing for precise alignment and capturing of image data before applying the pulsed beam, which induces plasma ablation and generates spectrum data for disease information analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a small spot size laser beam is used for spectroscopic analysis, then the spatial resolution and precision of the analysis point are improved, but the ability to clearly identify and consistently target the correct radiation position on the object deteriorates
Solution Approach 1:
The patent introduces guide light as an intermediary element that visually marks the radiation position on the object. This guide light serves as a mediator between the laser beam and the operator, making the invisible laser target position visible and easily identifiable, thereby resolving the contradiction between maintaining small spot size precision and improving position identification ease
Solution Approach 2:
The guide light creates a visual copy or representation of the laser radiation position on the object surface. This optical copy allows operators to see exactly where the laser will strike without the laser itself being visible, enabling precise positioning while maintaining the advantages of the small spot size laser beam
2Reliability
If multiple spectrum data sets from different radiation positions are collected, then the comprehensiveness and reliability of disease information is improved, but the time required for data collection and analysis increases
Solution Approach 1:
The guide light is activated before the laser radiation to pre-mark the target position on the object. This preliminary visual guidance allows operators to quickly and accurately position the laser without time-consuming trial and error adjustments, enabling efficient collection of multiple spectrum data sets from different positions while maintaining high reliability
Solution Approach 2:
The guide light provides real-time visual feedback about the laser radiation position on the object. This feedback mechanism allows operators to immediately verify correct positioning and make rapid adjustments, facilitating efficient collection of comprehensive spectrum data from multiple positions without significant time loss
