Three-Laser Phase Distance Measurer for Small-Target Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laser distance measurers face inaccurate measurements due to the visible and invisible lasers failing to irradiate the same small-sized target, caused by the physical separation of the bracket device.
Innovation Solution
A three-laser phase distance measurer with an outer and visible light path focusing-emitting devices arranged adjacent and side by side, along a horizontal or vertical direction, ensuring both lights irradiate the same target, accompanied by optical filters and a receiver to process and adjust the light paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a bracket device with visible light path focusing-emitting device and external light path focusing-emitting device is provided at two sides, then the user can see the visible light path for aiming, but the visible light and invisible distance measuring laser cannot irradiate the same small measured target due to the size of the bracket device
Solution Approach 1:
The patent merges the visible light path focusing-emitting device and the external light path focusing-emitting device into a unified optical system with a common optical axis. This allows both the visible light and the invisible distance measuring laser to be emitted from the same location and irradiate the same measured target, eliminating the measurement error caused by spatial separation while maintaining the bracket device structure for visibility.
2Ease of operation
If the bracket device structure is used to separate visible and invisible light paths, then the user can clearly see the aiming light, but there is a certain distance between the visible light and invisible laser causing inaccurate measurement
Solution Approach 1:
The patent segments the optical system into distinct functional modules: the visible light path focusing-emitting device and the external light path focusing-emitting device are arranged as separate but aligned components within the bracket device. Each module can be independently optimized while maintaining their spatial relationship, allowing the visible light to guide aiming and the invisible laser to perform measurement on the same target.
