| 摘 要： | 论述了眼底照相机的原理和控制杂光及鬼像的方法。通过精心设计照明系统的接目物镜 ,使其各个光学表面产生的鬼像位于较理想的位置 ,并通过在照明光路中加入较少的黑点板予以消除。同时通过使照明系统的环行光阑与照相系统的孔径光阑处于相互共轭的位置上 ,达到消除照明系统产生杂光和鬼像的目的。

| Abstract: | A method for clear up the harmful light such as scatter light and central ghost in retinal camera was introduced. In designing the objective lens of the illumination, we set the ghost generated by some optical surfaces at nearly same position, and then added some black spot plates in the illumination path, also conjugated the ring like stop of the illumination system with the aperture stop of photography system. |
