Binocular Higher-Order Aberration Correction and Vision Analysis System

人眼像差对视功能具有重要影响。目前相关研究结果多在单眼条件下获得,为解决双眼像差对双眼视功能的影响等问题,搭建了一套双眼高阶像差校正与视觉分析系统。该系统采用哈特曼波前传感器和37单元变形反射镜对双眼像差进行测量和控制,并通过对控制器增益的优化设计,实现了对双眼像差的稳定闭环控制。视标显示器采用有机发光二极管微型显示器,其视频输入信号直接由计算机产生,可方便地实现多种视功能测试。利用该系统进行了初步的立体视觉实验,展示了该系统在双眼视功能测试方面的巨大潜力。双眼高阶像差校正与视觉分析系统的建立为未来双眼视功能的深入研究提供了必要的技术和设备支持。

Human aberration plays an important role in visual function. So far, relevant research findings are obtained mainly under monocular viewing conditions. To investigate the effects of binocular aberrations on binocular visual functions, a binocular higher-order aberration correction and vision analysis system is established. The proposed system employs Hartmann wavefront sensors and 37-element deformable mirrors to measure and control binocular aberrations. Through the optimization of the controller gain, it realizes stable closed-loop control of binocular aberrations. The organic light-emitting diodes are used as stimulus display. The input signals are generated directly by computers, making it convenient to implement various visual function tests. Employing the proposed system, a preliminary stereo vision experiment is carried out, its vast potential in binocular visual function testing is demonstrated. The binocular higher-order aberration correction and vision analysis system provides essential technology and equipment support for further binocular visual function research in the future.
