    • Light from an exit pupil (112) of an illumination unit (100) is directed to abeam splitter (102) which directs the light to an objective (104).The retina (128) is illuminated, if a real image of the exit pupil (112)of the illumination unit (100) and a real image of an entrance pupil (114) of a camera unit (106) are formable in a position ranging from the cornea (120) to the backside (126) of the crystalline lens (124) with the light. The objective (104) forms a real intermediate image (130) of the retina (128) between the objective (104) and the camera unit (106). The beam splitter (102) directs the light from the retina (128) to the camera unit (106), while causing the path (134) of the illumination and the path (132) of the imaging to deviate for non- overlapping images of the exit pupil (112) and the en- trance pupil (114)in the crystalline lens (124). A relay lens system (138) forms a real image of the intermediate image (130) on a detecting component (136) with the light reflected from the retina (128) for transforming the image into an electric form to be shown on a screen (150).
    • 来自照明单元的出射光的光被引导到将光引导到物镜的分束器。 如果照明单元的出射光瞳的真实图像和相机单元的入射光瞳的真实图像是可形成的,则视网膜被照亮。 目标形成了物镜与相机单元之间的视网膜的真实中间图像。 分束器将来自视网膜的光引导到相机单元,同时使得照明的路径和成像的路径偏离用于晶状体中出射光瞳和入射光瞳的非重叠图像。 中继透镜系统利用从视网膜反射的光在检测部件上形成中间图像的实际图像,以将图像转换成电子形式以在屏幕上显示。
