A laser Doppler interferometer was built for the precise measurement of intraocular optical distances in humans and chicks. A technique using Purkinje images was developed to position the chick's eye reproducibly. A computer algorithm for the objective analysis of the interference signal and determination of the optical distances is presented. The precision of this noncontact interferometric method for measuring the cornea-retina distance is better than ±20 µm.
为精确测量人类和雏鸡的眼内光学距离，构建了一台激光多普勒干涉仪。开发了一种利用浦肯野图像的技术，以可重复的方式定位雏鸡的眼睛。提出了一种用于干涉信号客观分析和光学距离测定的计算机算法。这种非接触式干涉测量方法测量角膜-视网膜距离的精度优于±20微米。
