Abstract

Off-axis full-field OCT is intended to enable cost-effective imaging of the retina for home diagnosis. Different to common FD-OCT systems, the lateral field of view is acquired in a single shot and the different axial layers are acquired sequentially. During acquisition, motion of the eye results in motion artifacts and misaligned layers. We present a method to track the axial and lateral position of the retina by analyzing the angle and divergence of the backscattered light with a lateral precision of 3.6 µm and an axial precision of 29 µm. This information can be used to correct motion induced errors.
