摘要
报道了一种可实现入瞳位置不变的超广角扫频光相干层析成像(OCT)系统,对成像系统的样品臂进行了建模和光学仿真, 证实其可行性和有效性。设计并展示了一个超广角OCT成像系统, 在仅改变振镜位置及透镜间距的情况下, 实现了超过40°的眼底单次超大角度扫描, 单次横向扫描范围覆盖眼底I区, 有效增加了OCT单次扫描的成像范围。
Abstract
Proposed is a swept-source optical coherence tomography (SS-OCT) system with ultra-wide field and invariable position of incident pupil. Modeling and optical simulations of the OCTs sample arm were carried out to verify the feasibility and effectiveness of the OCT system. And an SS-OCT system with ultra-wide field was designed and presented. With only changing the position of galvanometers and the distance between lens, more than 40° angle of a single transverse scan was realized, in which the total I area of fundus was covered. As a result, the imaging range of OCT in a single scan was effectively increased.
