Axial resolution enhancement for an OCT system implemented by mechanically induced long-period fiber grating
APBP 2004: SECOND ASIAN AND PACIFIC RIM SYMPOSIUM ON BIOPHOTONICS, PROCEEDINGS(2004)
摘要
We demonstrate a spectral filtering method that can enhance the axial resolution of an OCT system. A mechanically induced long-period grating was used to tailor the spectral shape of an in-house made Er-doped fiber amplified spontaneous emission source. The proposed method improved the visibility of the OCT image dramatically.
