Axial Superresolution in Optical Coherence Tomography
光学相干层析成像轴向超分辨研究

Optical superresolution is adopted for axial resolution enhancement in optical coherence tomography (OCT).Three-zone phase and amplitude pupil filters were designed and implemented in the sample arm of OCT system. Axial response curves measured under different conditions are in good agreement with the theoretical analyses. Comparison results achieve an improvement of more than 10%, demonstrating the feasibility of axial superresolution in OCT by use of appropriate pupil filters.
