A new visual acuity testing device is able to determine a specific visual acuity of the retina even in the presence of opacities of the ocular media, such as a cataract. This is achieved by forming two spatially coherent, quasimonochromatic point sources near the nodal point of the eye. The two spherical waves that emanate from the point sources interact to produce a pattern of stripes on the retina. The intensity of the pattern is easily varied. More importantly, the pattern can be projected over different-sized retinal areas corresponding to visual fields of 0.5 to 15 degrees in diameter. The device may be useful for vision research and preoperative assessments of visual potential.
一种新型视力测试设备即使在存在诸如白内障等眼介质混浊的情况下，也能够确定视网膜的特定视力。这是通过在眼睛的节点附近形成两个空间相干的准单色点光源来实现的。从点光源发出的两个球面波相互作用，在视网膜上产生条纹图案。该图案的强度很容易改变。更重要的是，该图案可以投射到对应于直径为0.5至15度视野的不同大小的视网膜区域上。该设备可能对视觉研究和视觉潜能的术前评估有用。
