Lens-Based Optical Path Extension for Laser Level Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional laser level calibration methods require a fixed, large physical distance between the laser level and detector, imposing space constraints and introducing interference factors.
Innovation Solution
An optical path extension device is used to optically enlarge the distance between the laser level and detector, allowing calibration without changing the physical distance, using components like objective lenses, focusing lenses, and eyepieces to project the laser.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a fixed large physical distance (5m or 10m) is used for calibration, then calibration accuracy can be improved, but space requirements increase and interference factors are introduced
Solution Approach 1:
An optical path extension device is introduced as an intermediary component between the laser level and detector. This device includes optical elements (lenses, mirrors) that extend the optical path length without proportionally increasing the physical distance, thereby maintaining calibration accuracy while reducing space requirements and minimizing interference factors
Solution Approach 2:
The patent replaces the mechanical approach of physically separating the laser level and detector by a large distance with an optical approach. The optical path extension device uses optical mechanisms (lenses, mirrors) to achieve the equivalent of a long baseline calibration within a compact physical space
2Measurement precision
If a fixed large physical distance is used for calibration, then calibration accuracy can be improved, but the device complexity and space requirements increase
Solution Approach 1:
The optical path extension device is designed to be integrated into the existing laser level calibration system, serving multiple functions: extending the optical path, maintaining alignment, and reducing the physical footprint. This multi-functionality avoids adding significant complexity while achieving the goal of improved calibration accuracy
