    摘要： It is provided an ophthalmic optical coherence tomography system in the invention, the system comprising: an OCT interferometer primary module and a sample arm module, wherein the OCT interferometer primary module comprises an OCT light source, a fiber coupler, a reference arm, a detection module, an X-direction scanning unit, and a Y-direction scanning unit; the sample arm module comprises an anterior eye segment imaging module and a posterior eye segment imaging module; the Y-direction scanning unit is rotatable; when the Y-direction scanning unit is at a first rotation angle, the Y-direction scanning unit reflects the light received by the X-direction scanning unit into the anterior eye segment imaging module; and when the Y-direction scanning unit is at a second rotation angle, the Y-direction scanning unit reflects the light received by the X-direction scanning unit into the posterior eye segment imaging module. It is further provided a method for quick switching to realize anterior and posterior eye segments imaging in the invention, in which imaging at one time and quick switching for locations at different depths can be realized, and on this basis, the eye axial length can be measured accurately.

    摘要翻译： 本发明提供了一种眼科光学相干断层摄影系统，该系统包括：OCT干涉仪主模块和样本臂模块，其中OCT干涉仪主模块包括OCT光源，光纤耦合器，参考臂，检测 模块，X方向扫描单元和Y方向扫描单元; 样本臂模块包括前眼部分成像模块和后眼部成像模块; Y方向扫描单元可旋转; 当Y方向扫描单元处于第一旋转角时，Y方向扫描单元将由X方向扫描单元接收的光反射到前眼部成像模块中; 并且当Y方向扫描单元处于第二旋转角度时，Y方向扫描单元将由X方向扫描单元接收的光反射到后眼部成像模块中。 本发明还提供了快速切换以实现前后眼部成像的方法，其中可以实现一次成像并且可以实现不同深度位置的快速切换，并且在此基础上，眼轴长度可以是 准确测量。
