摘要
介绍一种新的激光视网膜功能仪,运用激光杨氏干涉光学系统,排除屈光不正及晶状体缺陷的影响,使视网膜直接接受干涉条纹,直接测得视网膜的分辨本领。仪器结构紧凑,操作简便,测定结果可直接读得与经典同际 E 字表相符合的视力值。
A recent developed laser retinometer is introduced in this paper.It uses the laserinterferential optical system.This method can get rid of influence of ametropia and lenticulardefect.The retina can accept the interference-fringe straight,so it can determine the retinal reso-lving power.Its design and structure is rational,light and compact,it operates easy.Measuringresult can accord with classics national“E”vision form.
