# Depth-of-focus extension in optical coherence tomography via multiple aperture synthesis MATLAB code for performing multiple aperture synthesis. This algorithm aims to digitally synthesize five distinctive cross-sectional images of 6um beads captured via five distinctive apertures into one brand new DOF-extended image.
