Laser Gas Analyzer Dual Display Optical Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser gas analyzers require two workers to perform optical axis adjustments due to the difficulty in visually checking the transmittance of laser light, leading to inefficient processes, especially in setups with long smoke ducts where slight offsets significantly reduce transmittance.
Innovation Solution
A laser gas analyzer design featuring a main display on the light receiver and a sub-display on the light emitter, allowing one worker to efficiently perform optical axis adjustments by displaying measurement results and transmittance information, enabling independent alignment without the need for communication devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical axis adjustment is performed using traditional methods with separate workers for light emitter and light receiver, then measurement accuracy can be maintained, but task efficiency decreases due to requiring two workers and communication devices
Solution Approach 1:
The patent applies the copying principle by displaying the measurement results from the light receiver on a display device at the light emitter side. This allows the worker at the light emitter to see the same information that would otherwise be visible only at the light receiver, enabling single-worker operation while maintaining alignment accuracy.
Solution Approach 2:
The display device acts as an intermediary that transfers the measurement result information from the light receiver to the light emitter location. This intermediary enables the worker to access transmittance information remotely without needing to physically move to the light receiver or use communication devices.
2Length of stationary object
If the smoke duct diameter is increased to several tens of meters, then the measurement range is improved, but transmittance decreases significantly with slight optical axis offsets
Solution Approach 1:
The patent implements feedback by displaying the transmittance measurement results in real-time on a display device during optical axis adjustment. This allows the worker to immediately see the effect of any optical axis offset and make precise adjustments to maximize transmittance, which is critical for long smoke ducts where even slight offsets cause significant transmittance loss.

Function Achieved in This Case
This configuration allows a single worker to efficiently perform optical axis adjustments, improving task efficiency and reducing the need for dual worker operations, even in setups with longer smoke ducts where transmittance decreases with slight axis offsets.
Implementation Method 1
measures components contained in a gas to be measured and the concentration, etc., thereof based on the absorption spectrum of a laser light which transmits the gas to be measured
