Suppression of autocorrelation artifacts in PS-OCT images based on spectral phase interpolation
Abstract
Polarization-maintaining (PM) fiber-based polarization-sensitive optical coherence tomography (PS-OCT) system has high stability and portability. However, PM fibers may introduce different kinds of artifacts. A spectral phase interpolation method is proposed to suppress the autocorrelation artifacts in this Letter, in which the reference phase is calculated based on each A-scan signal, and the calculated reference phase is used to perform phase interpolation in the original interference signal. Experimental results from the ex vivo porcine eye demonstrate that autocorrelation artifacts in PS-OCT images can be effectively eliminated and the original image information is perfectly recovered at artifacts.
