An additional unit which can be used for length measurements at the fundus of the human eye is described for the ophthalmoscope. The principle of measurement is based on optical displacement of the measuring object to itself. The optical displacement of picture points is made possible by the use of a tilting flat glass plate in the intermediate image plane of the eyepiece. The relation between the optical displacement of picture points and the measuring movement is sufficiently linear for the described device.
本文介绍了一种可用于眼底长度测量的附加装置，该装置用于检眼镜。测量原理基于测量对象自身的光位移。通过在目镜的中间像平面中使用倾斜的平板玻璃，实现了图像点的光位移。对于所描述的装置，图像点的光位移与测量移动之间的关系具有足够的线性度。
