Typical fundus photography produces a two-dimensional image. This makes it difficult to observe the microvascular and neural abnormalities, because the depth of the image is missing. To provide depth appreciation, we develop a single-channel stereoscopic fundus video imaging system based on a rotating refractor. With respect to the pupil center, the rotating refractor laterally displaces the optical path and the illumination. This allows standard monocular fundus cameras to generate stereo-parallax and image disparity through sequential image acquisition. We optimize our imaging system, characterize the stereo-base, and image an eyeball model and a rabbit eye. When virtual realities are considered, our imaging system can be a simple yet efficient technique to provide depth perception in a virtual space that allows users to perceive abnormalities in the eye fundus.

使用单通道立体显微镜对眼底图像的深度感知

典型的眼底摄影会产生二维图像。这使得难以观察微血管和神经异常，因为图像的深度缺失。为了提供深度欣赏，我们开发了一种基于旋转折射镜的单通道立体眼底视频成像系统。相对于瞳孔中心，旋转折射镜横向移动光路和照明。这允许标准单目眼底相机通过顺序图像采集来生成立体视差和图像差异。我们优化了我们的成像系统，对立体基础进行了表征，并对眼球模型和兔眼进行了成像。当考虑虚拟现实时，
