摘　　要：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 sys-tem 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 opti-mize 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 abnor-malities in the eye fundus.
