Range Finding Binocular Telescope Laser Path Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Typical range finding binocular telescopes suffer from significant laser power loss due to the mixing of laser transmitting and receiving paths with observation light paths through prism groups, leading to decreased accuracy and complex adjustments.
Innovation Solution
The design separates the laser transmitting and receiving paths from the observation light path using distinct lens bodies and prism groups, allowing independent adjustment and reducing the number of reflective surfaces, thereby enhancing laser power and simplifying adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the laser transmitting path and laser receiving path are mixed in the prism group with the observation light path, then the device structure is compact, but the laser power decreases significantly due to passing through too many surfaces
Solution Approach 1:
The patent divides the optical system into separate laser transmitting module and laser receiving module, each with dedicated prism groups. The laser transmitting path and laser receiving path are physically separated from the observation light path, reducing the number of reflective surfaces the laser beams must pass through and minimizing energy loss.
Solution Approach 2:
The invention extracts the laser transmitting and receiving paths from the mixed optical system, creating independent laser modules. This separation removes the laser paths from the complex prism group that the observation light path uses, thereby reducing unnecessary energy loss while maintaining compact device structure.
2Length of stationary object
If the laser power is increased to measure long-distance objects, then the measurement range is extended, but the risk of laser path leakage to the eyepiece group increases
Solution Approach 1:
The patent implements separate laser transmitting and receiving modules with distinct optical paths. The laser transmitting path is isolated from the eyepiece group through dedicated optical components and separate prism groups, preventing laser leakage even at high power levels while extending measurement range.
3Device complexity
If the laser transmitting path and observation light path are mixed in the prism group, then the device structure is simplified, but the adjustment process becomes too complicated
Solution Approach 1:
The invention separates the laser transmitting module and laser receiving module as independent units, each with its own adjustment mechanisms. This modular segmentation allows independent adjustment of laser paths without affecting the observation light path, simplifying the overall adjustment process despite maintaining a compact device structure.
Solution Approach 2:
The patent incorporates adjustable components within the laser modules that allow dynamic adjustment of the laser transmitting and receiving paths. These independent adjustment mechanisms enable operators to optimize laser alignment separately from the observation system, reducing adjustment complexity.
