用于OCT探针的单片光束成形光学系统以及方法
摘要：
公开了用于光学相干断层扫描(OCT)探针的单片光束成形光学系统以及方法，该光学相干断层扫描(OCT)探针包括具有不对称的光焦度的透明圆柱形外壳。该系统包括透明单片体(110)，该透明单片体(110)具有折叠的光轴以及至少一个对准特征，该至少一个对准特征支撑光纤的与有角度的平面端壁(160)相邻的末端。单片体还包括限定物面和像面的全内反射表面(170)和透镜表面(204)。来自光纤末端的光穿过包括驻留在透镜表面和像面之间的圆柱形外壳的光路。透镜表面自身或透镜表面和反射(例如，TIR)表面的结合被配置成基本上校正了圆柱形外壳的不对称的光焦度，从而在像面(IMP)处形成基本上旋转对称的图像斑点(380)。
摘要（英）：

Monolithic beam-shaping optical systems and methods are disclosed for an optical coherence tomography (OCT) probe. The optical coherence tomography (OCT) probe includes a transparent cylindrical housing having asymmetric optical power. The system includes a transparent monolithic body (110) having a folded optical axis and at least one alignment feature (that supports the end of an optical fiber adjacent an angled planar end wall (160). The monolithic body also includes a total-internal reflection surface (170) and a lens surface (204) that define object and image planes. Light from the optical fiber end traverses the optical path, which includes the cylindrical housing residing between the lens surface and the image plane. Either the lens surface by itself or the lens surface and the reflective (eg, TIR) surface in combination are configured to substantially correct for the asymmetric optical power of the cylindrical housing, thereby forming a substantially rotationally symmetric image spot (380) at the image plane (IMP).
