Abstract
Image artifacts due to the bulk motion of the sample are well known and described. Some methods of correction in Full-Filed Swept-Source OCT were presented. For the measurement of dynamic sample motion, the axial motion artifacts can significantly influence measured signals. Here, we investigate the axial shift phenomena for measurements with low cost, reduced speed swept laser. Simulation results have led us to the way of correction of the axial shift artifact by manipulation of the phase of OCT fringes. Results of disturbed and undisturbed measurement of vibrating speaker membrane or induced deformations of the porcine eye are presented.
