Paper Abstract

Aperture synthesis techniques such as Interferometric Synthetic Aperture Microscopy (ISAM) and digital refocusing allow to restore Optical Coherence Tomography (OCT) images in out-of-focus regions and obtain increased spatial resolution. Since these techniques are phase sensitive, they require object stability during OCT data acquisition. Since these techniques are manipulate volumetric data as well, application of the techniques to in vivo measurements require some motion correction procedure. In this work we will show that some of these correction procedures can obliterate not only local phase variations caused by the objects motion during the acquisition but local phase variations caused by defocusing, thus erasing information necessary for OCT image restoration. Ways of overcoming the problem are presented and discussed.
