PS-OCT探头如图1所示。我们分别在OCT系统的样品臂和参考臂中集成了两个GRIN透镜。样品臂中的GRIN透镜用于内窥镜成像，而参考臂中的GRIN透镜有助于色散补偿。我们的系统可以通过将GRIN透镜插入组织来捕获内部组织结构。根据图2所示的结果，可以基于不同的OCT成像特征来区分不同的硬膜外组织。
The PS-OCT probe is demonstrated in Fig. 1. We integrated two GRIN lenses in the sample arm and reference arm of the OCT system, respectively. The GRIN lens in the sample arm is employed for endoscopic imaging, while the one in the reference arm aids in dispersion compensation. Our system can capture internal tissue structures by inserting the GRIN lens into the tissue. From the results shown in Fig. 2, different epidural tissues can be distinguished based on the different OCT imaging features.
