摘要：
提供光学相干断层成像术OCT成像系统和激光扫描系统。OCT系统提供有：耦合至OCT成像系统的采样臂的宽带光辐射源；采样臂中的光束成形光学组件，所述光束成形光学组件用于接收来自源的光辐射作为光辐射束，以及用于对光辐射束的空间分布进行成形；耦合至光束成形光学组件的扫描镜组件；以及耦合至光束成形光学组件的物镜组件。在激光扫描系统中也提供用于接收来自激光源的光辐射的光束成形光学组件。两个系统的光束成形光学组件均包括透镜组件，透镜组件用于：在不改变焦点的情况下，改变OCT系统的NA；在不改变系统的NA的情况下，改变OCT系统的焦点；或者响应于控制输入改变OCT系统的NA和焦点。
摘要（英）：

Optical coherence tomography (OCT) imaging systems are provided including a source of broadband optical radiation coupled to a sample arm of the OCT imaging system; a beam shaping optical assembly in the sample arm, the beam shaping optical assembly being configured to receive optical radiation from the source as a beam of optical radiation and to shape the spatial profile of the beam of optical radiation; a scan mirror assembly coupled to the beam shaping optical assembly; and objective lens assembly coupled to the beam shaping optical assembly. The beam shaping optical assembly includes a lens assembly configured to change a NA of the OCT system without changing a focus; to change a focus of the OCT system without changing a NA of the system; or to change both the NA and the focus of the OCT system responsive to a control input.
