摘要： In exemplary implementations, this invention comprises apparatus for retinal self-imaging. Visual stimuli help the user self-align his eye with a camera. Bi-ocular coupling induces the test eye to rotate into different positions. As the test eye rotates, a video is captured of different areas of the retina. Computational photography methods process this video into a mosaiced image of a large area of the retina. An LED is pressed against the skin near the eye, to provide indirect, diffuse illumination of the retina. The camera has a wide field of view, and can image part of the retina even when the eye is off-axis (when the eye's pupillary axis and camera's optical axis are not aligned). Alternately, the retina is illuminated directly through the pupil, and different parts of a large lens are used to image different parts of the retina. Alternately, a plenoptic camera is used for retinal imaging.

摘要翻译： 在示例性实施方式中，本发明包括用于视网膜自我成像的装置。 视觉刺激帮助用户用相机自行调整眼睛。 双眼耦合引起测试眼旋转到不同的位置。 当测试眼旋转时，捕获视网膜的不同区域的视频。 计算摄影方法将该视频处理成视网膜大面积的马赛克图像。 LED被压在眼睛附近的皮肤上，以提供视网膜的间接的漫射照明。 相机具有宽视野，即使眼睛离轴（眼睛的瞳孔轴和相机的光轴未对齐），也可以对视网膜的一部分进行成像。 或者，视网膜直接通过瞳孔照射，并且使用大透镜的不同部分来对视网膜的不同部分进行成像。 或者，全视相机用于视网膜成像。
