利用双眼自适应光学(AO)视觉仿真器测量了两种不同亮度条件(1和100 cd/m2)下人眼像差对双眼对比敏感度和双眼叠加作用的影响，并针对2 c/d，8 c/d和16 c/d(周期每度)三种不同的信号空间频率进行了测试。实验结果表明，自适应光学像差矫正能够使得双眼对比敏感度函数呈现出各个测试频率上的整体升高。在两种亮度条件下，双眼对比敏感度收益与单眼相比均无统计上的显著差异(p>0.05)。在中高频范围(8 c/d、16 c/d)，单双眼的AO像差矫正收益均随亮度的升高而升高。对于本文测试的三种信号频率，高亮度条件下的AO像差矫正对双眼叠加作用无显著影响，而在低亮度条件下，AO 像差矫正使双眼叠加作用降低。本文为不同亮度下的双眼视觉信息处理机制提供了重要依据。

A binocular Adaptive Optics (AO) visual simulator was used to study the effect of ocular aberrations on binocular contrast detection in three spatial frequencies (2 c/d, 8 c/d and 16 c/d) and two light levels (1 and 100 cd/m2). For all conditions, AO correction of ocular aberrations improved the binocular/monocular contrast sensitivity significantly. For both light levels, the binocular AO benefits in contrast sensitivity showed no significant difference with the benefits achieved monocularly. For signal at 8 c/d and 16 c/d, the visual benefits increased with the increase of light level. For all tested signal at three spatial frequencies, binocular summations were similar for conditions with and without AO correction of ocular aberrations at high light level. For low light level, binocular summation slightly decreased with AO correction. Our findings expand the knowledge on how ocular aberrations affect the binocular contrast detection in different light levels, while also improving the understanding of visual processing.
