Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical fiber imaging systems suffer from deviations in the optical fiber image due to noise interference, leading to inaccuracies in pixel signals, which cannot be effectively addressed by current methods.
Innovation Solution
A real-time correction method that calculates a correction coefficient based on optical fiber pairs formed by the centers of optical fiber bundles, using a mathematical model to determine a corrected signal by multiplying the original signal with a gain parameter and adding a bias parameter, while discarding zero grayscale value and outlier data to enhance accuracy.

Engineering Contradiction Analysis
1Measurement precision
If real-time correction is performed on optical fiber image signals, then image accuracy is improved, but device complexity increases due to the need for calculating correction coefficients and processing optical fiber pairs
Solution Approach 1:
The system uses the optical fiber image data itself to calculate the correction coefficients. By analyzing the spatial relationships and intensity variations within the image data, the system self-determines the correction parameters without requiring external calibration equipment or additional sensors, thus improving accuracy while limiting complexity growth.
Solution Approach 2:
The patent transforms the correction problem into parameter estimation by modeling the relationship between optical fiber positions and image intensities. Correction coefficients (gain and offset parameters) are calculated based on observed intensity variations, converting a complex spatial correction problem into a manageable parameter optimization task.
2Measurement precision
If correction coefficients are calculated using optical fiber pairs, then noise-induced deviations are eliminated, but calculation complexity increases due to pair formation and correlation analysis
Solution Approach 1:
The patent divides the optical fiber bundle into pairs of fibers for analysis. By segmenting the complex multi-fiber system into manageable pairs, the calculation of correction coefficients becomes more tractable while still capturing the essential spatial relationships needed for accurate noise correction.
Solution Approach 2:
The system uses correlation analysis of optical fiber pairs to provide feedback on signal quality and drift conditions. This feedback mechanism allows the system to adaptively adjust correction coefficients based on real-time observations of fiber position variations and noise patterns, improving accuracy without requiring complex external control systems.
