Abstract

A novel method is proposed for correcting aberrations and diffraction-induced artifacts in optical coherence tomography (OCT) images. The method leverages light backpropagation models combined with region-based despeckling and sharpness optimization algorithms to improve overall OCT image quality across a variety of sample types. The algorithm was applied to data acquired using a Line-Field OCT (LF-OCT) system with high numerical aperture (NA) and short depth-of-focus (DOF) Significant improvements were made to images acquired at different depths within various sample types. Such improvement holds the promise of providing ultra-high resolution volumetric OCT data without the need for depth scanning.
