Abstract

This article focuses on a spectral phase interpolation method developed to suppress autocorrelation artifacts in polarization-maintaining (PM) fiber-based polarization-sensitive optical coherence tomography (PS-OCT) systems. Autocorrelation artifacts, caused by Fresnel reflections and dual polarization modes in PM fibers, appear as horizontal lines that degrade image quality and are challenging to eliminate with existing techniques. The proposed method calculates a reference phase from the strongest artifact in each A-scan and uses it to perform phase interpolation on the original interference signal, effectively aligning spectral phases and removing artifacts without compromising image information. Experimental validation on ex vivo porcine eye samples demonstrated that this approach significantly reduces autocorrelation artifacts in intensity, optic axis, and retardation images, restoring original image details and enhancing the imaging quality of PM fiber-based PS-OCT systems.
