Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time correction is performed on optical fiber images, then image accuracy is improved, but device complexity increases due to the need for calculating correction coefficients using optical fiber pairs
Solution Approach 1:
The optical fiber image correction system uses the optical fiber pairs within the image itself to generate correction coefficients, allowing the system to self-correct without requiring external calibration devices or complex additional hardware. The optical fiber centers in the image are utilized to automatically determine correction parameters.
Solution Approach 2:
The system dynamically calculates and applies correction coefficients that change based on the specific image being processed. These coefficients adjust parameters such as gain and offset for different regions of the optical fiber image, enabling adaptive correction without fixed predetermined values.
2Measurement precision
If optical fiber drift is corrected using traditional methods, then scanning position accuracy is improved, but processing time increases due to frame-by-frame analysis
Solution Approach 1:
The system performs preliminary identification of optical fiber centers and pairs in advance, establishing a foundation for rapid correction coefficient calculation. By pre-processing the image to locate fiber centers, the system reduces the computational burden during actual correction.
Solution Approach 2:
The patent replaces traditional mechanical or manual correction methods with an automated computational approach using optical fiber pair correlation. This substitution enables faster, real-time correction without the time-consuming manual intervention previously required.
3Measurement precision
If noise is reduced in optical fiber signals, then signal accuracy is improved, but information loss increases due to aggressive filtering
Solution Approach 1:
The optical fiber pairs act as intermediaries to extract correction information from the noisy signal. By using the spatial relationship and correlation between fiber pairs, the system can distinguish true signal patterns from noise without requiring aggressive filtering that would remove useful information.
Solution Approach 2:
The system uses the correlation information from optical fiber pairs to provide feedback on signal quality and correction effectiveness. This feedback mechanism allows the system to adjust correction parameters dynamically, maintaining signal accuracy while preserving important signal details that might otherwise be lost.
