Binocular Telescope Laser Ranging Path Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In typical binocular telescopes, the mixing of laser transmitting and receiving paths with the observation light path leads to a significant decrease in laser power and increased risk of laser leakage, along with complex adjustments due to shared prism groups.
Innovation Solution
The binocular telescope design separates the laser ranging path from the observing light path, with independent laser transmitting and receiving modules positioned in front of the lens bodies, reducing the number of reflect surfaces and allowing for independent adjustments of both systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the laser transmitting path and laser receiving path are mixed in the prism group with the observation light path, then the structure is integrated, but the laser power decreases significantly due to passing through too many surfaces
Solution Approach 1:
The patent divides the optical system into separate modules: the laser transmitting path and laser receiving path are physically separated from the observation light path. The laser transmitting module includes a laser emitter, transmitting lens, and transmitting mirror, while the laser receiving module includes a receiving lens and receiving mirror. This segmentation allows each module to have its own independent optical path, reducing the number of surfaces laser beams must pass through and minimizing energy loss.
Solution Approach 2:
The patent extracts the laser ranging function from the integrated prism group structure. By taking out the laser transmitting and receiving paths from the common observation optical path, the design eliminates the need for laser beams to pass through multiple prism surfaces. The laser paths are independently configured with dedicated transmitting and receiving modules, thereby preserving laser power while maintaining the observation function separately.
2Length of moving 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 segments the optical paths so that the laser transmitting path is physically separated from the observation light path that reaches the eyepiece. The laser beams travel through dedicated transmitting and receiving modules with independent optical axes, preventing laser leakage into the eyepiece group even when high power is used for long-distance measurement.
Solution Approach 2:
The laser ranging function is extracted from the common observation path and implemented as an independent module. This extraction ensures that increased laser power for extended measurement range does not create harmful leakage effects in the observation path, as the two functions operate through separate optical channels.
3Volume of stationary object
If the laser path and observation light path are mixed in the prism group, then the structure is compact, but the adjustments become too complicated
Solution Approach 1:
The patent segments the optical system into independent modules with separate adjustment mechanisms. The laser transmitting module, laser receiving module, and observation optical path each have their own adjustment components, allowing independent optimization without affecting other parts. This modular segmentation simplifies the adjustment process compared to a mixed system where adjustments would affect multiple functions simultaneously.
Solution Approach 2:
The patent introduces dynamic adjustment capabilities for each independent module. The laser transmitting and receiving paths can be adjusted independently of the observation path, allowing real-time optimization of each function. This dynamic independence reduces adjustment complexity by allowing targeted adjustments rather than system-wide recalibration.
