Abstract
We present in vivo human fundus imaging using a fiber-based confocal scanning laser ophthalmoscope (SLO). Spectrally encoded confocal scanning laser ophthalmoscopy (SECSLO) utilizes a spectral encoding technique in one dimension, combined with single-axis lateral scanning, to create video-rate reflectivity maps of the fundus. This implementation of the SLO allows for high-contrast high-resolution in vivo human retinal imaging through a single-mode optical fiber. We experimentally quantify the full confocality of SECSLO in both the spectrally encoded and laterally scanned dimensions, and demonstrate 50 Hz frame rate fundus imaging.
摘要
我们使用基于光纤的共焦扫描激光检眼镜（SLO）呈现体内人眼底图像。光谱编码共焦扫描激光检眼镜（SECSLO）在一维中利用光谱编码技术，结合单轴横向扫描，创建眼底反射率的视频速率图。这种 SLO 的实现允许通过单模光纤进行高对比度、高分辨率的体内人视网膜成像。我们在光谱编码和横向扫描两个维度上实验性地量化了 SECSLO 的完全共聚焦性，并展示了 50 Hz 帧频的眼底成像。
