Abstract
This work demonstrates that the phase-based decorrelation compensation method outperforms the amplitude-based approach in low signal-to-noise ratio (SNR) regions of phase-sensitive optical coherence tomography (PhS-OCT). Building on this finding, an adaptive decorrelation compensation approach for digital-image-correlation (DIC)-assisted PhS-OCT is introduced. This method utilizes the maximum correlation coefficient from amplitude maps to adaptively determine the need for secondary tracking of decorrelated displacement using the phase-based approach. It significantly improves decorrelation compensation quality while minimizing impacts on computational efficiency. A tensile testing experiment was conducted to validate the method, with results showing that the proposed adaptive compensation method enables previously unmeasurable low SNR regions to become measurable by adaptively retracking only 21.7% of the area.
