A binocular adaptive optics visual simulator has been devised for the study of stereopsis and of binocular vision in general. The apparatus is capable of manipulating the aberrations of each eye separately while subjects perform visual tests. The correcting device is a liquid-crystal-on-silicon spatial light modulator permitting the control of aberrations in the two eyes of the observer simultaneously in open loop. The apparatus can be operated as an electro-optical binocular phoropter with two micro-displays projecting different scenes to each eye. Stereo-acuity tests (three-needle test and random-dot stereograms) have been programmed for exploring the performance of the instrument. As an example, stereo-acuity has been measured in two subjects in the presence of defocus and/or trefoil, showing a complex relationship between the eye's optical quality and stereopsis. This instrument might serve for a better understanding of the relationship of binocular vision and stereopsis performance and the eye's aberrations.
已设计出一种双目自适应光学视觉模拟器，用于一般立体视觉和双目视觉的研究。该仪器能够在受试者进行视觉测试时分别控制每只眼睛的像差。校正装置是一个硅基液晶空间光调制器，可在开环状态下同时控制观察者两只眼睛的像差。该仪器可作为一个电光双目综合验光仪使用，通过两个微型显示器向每只眼睛投射不同的场景。已编制了立体视敏度测试程序（三针测试和随机点立体图），以探究该仪器的性能。例如，已在两名受试者身上测量了存在散焦和/或三叶像差时的立体视敏度，结果表明眼睛的光学质量与立体视觉之间存在复杂关系。该仪器可能有助于更好地理解双目视觉与立体视敏度性能以及眼睛像差之间的关系。
