VCSEL Coaxial Visualization Layout for Direct Laser Field Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser systems for medical treatment lack coaxial visualization, requiring separate field-of-view observation devices and complex coordinate conversions due to non-coaxial imaging light, making direct observation of the therapy field impossible.
Innovation Solution
A laser design incorporating a VCSEL planar array light source, imaging lens, planar reflector, and optical window, where the planar reflector deflects VCSEL laser light to form a real image coaxially with the observation position, allowing for direct observation of the therapy field through a CCD imaging device or magnifying glass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate field-of-view observation devices are used, then observation capability is provided, but device complexity and coordinate conversion requirements increase
Solution Approach 1:
The patent combines the field-of-view observation device with the laser therapeutic instrument handpiece into a single integrated unit. The imaging light source and laser beam are made coaxial, allowing the observation device to be merged with the laser delivery system. This eliminates the need for separate observation devices and complex coordinate conversions, directly resolving the technical contradiction by integrating multiple functions into one device.
2Ease of operation
If imaging light is non-coaxial with laser beam, then separate observation is possible, but direct observation of therapy field becomes impossible
Solution Approach 1:
The patent makes the imaging light coaxial with the laser beam by integrating the imaging light source with the laser delivery system. The imaging lens is positioned on the main optical axis of the VCSEL planar array light source, ensuring that the imaging light and laser beam share the same optical path. This coaxial design enables direct observation of the therapy field along the laser beam path, eliminating the need for separate observation devices and complex coordinate conversions.
3Power
If VCSEL planar array light source is used, then laser output is provided, but heat generation increases
Solution Approach 1:
The patent introduces a heat sink as an intermediary component between the VCSEL planar array light source and the housing. The heat sink absorbs and dissipates the heat generated by the VCSEL light source, acting as a thermal mediator that protects other components from excessive heat while maintaining the high laser output power. This allows the system to maintain high power output without excessive temperature rise affecting system performance.
