title: Motion correction using overlapped data correlation based on a spatial-spectral encoded parallel optical coherence tomography.
abstract: This paper presents an approach to remove motion artifacts based on a spatial-spectral encoded parallel OCT (SSE-POCT) system, where encoded rectangular illumination is employed. Motion artifacts within a B-scan are avoided due to parallel detection intrinsic to parallel OCT, while those between successive B-scans are estimated and corrected by a proposed overlapped data correlation (ODC) algorithm. To preserve axial resolution, decoded B-scan corresponding to complete spectrum is stitched from successive encoded B-scans after motion correction. Imaging is conducted on several samples under preset motion trajectories, and OCT images with unnoticed motion artifacts and well-preserved resolutions are reconstructed. The approach based on the developed SSE-POCT system and the proposed ODC algorithm for motion correction can be applicable for in vivo imaging where uncontrolled motion is usually unavoidable.
