目前在眼科临床上用视力表检查人眼睛的视力,这种视力检查是测定与眼球成象系统和视网膜适应状态有关的综合功能。采用激光干涉技术可以单独测定视网膜的功能。这种方法是以相干的激光作光源把光分为两束。在被试者眼球节点附近形成两个相干的小光点,这
Eye vision is currently used in ophthalmology to check the visual acuity of the human eye. This visual acuity test is a comprehensive function that determines the state of adaptation of the eye imaging system and the retina. Using laser interferometry can measure retinal function alone. This method is based on coherent laser light source to split the light into two beams. In the subjects near the eyeballs formed two coherent little light spots, this
