介绍了利用双光束干涉法检查眼底视觉功能(分辨力)的基本原理,描述了我们研制的激光干涉视力仪的光路系统,以及对眼科常见病90例,125只眼的检查结果,指出了“星点闪烁”现象在眼底视觉测定中的重要意义。 The principle of using double beam interferometry to examine the visual function (resolution) of the fundus is introduced. The optical system of the laser interferometer is described, as well as the examination results of 90 eyes and 125 eyes of common ophthalmology, Star flicker "phenomenon in the visual determination of the significance of the eye.
