Abstract

Ophthalmic optical coherence tomography (OCT) is a powerful tool which provides high resolution three dimensional (3D) volumetric image of human retina. However, the measurement data of OCT suffer motion artifact due to the involuntary eye motion during data acquisition. To eliminate this motion artifact and provide the true shape of retinal image, an eye motion corrected OCT imaging method based on Lissajous scan pattern is proposed in this paper. In this approach, we adopted Lissajous scan pattern for 3D-OCT imaging and developed motion correction algorithm. To verify the effectiveness of this method, we compare our method with single raster scan method by the experimental results. The experimental results show that the eye motion can be corrected by our method effectively.
