Multi-scale hybrid visual impairment analyzer and analysis method thereof

Abstract

The invention relates to the field of medical instruments, in particular to a multi-scale hybrid visual impairment analyzer used for real-time analysis of sensing stimuli on an expanded retina. The analyzer comprises a lighting unit, an imaging unit, a multi-scale stimulation generator unit, a processing unit, an optical compensation unit, a pupil monitoring unit and a fixed target unit. The lighting unit is used for providing at least one optical probe for different layers of the eyes for performing eye analysis; the imaging unit is used for capturing retinal images on the entire view field of the multi-scale stimuli; the multi-scale stimulation generator unit is used for displaying the images with ultra-high resolution under control of multiple field domains, has visible light sensitivity and is capable of outputting the controllable fuzzy stimuli; the processing unit is used for stabilizing the stimuli in a large view field for retinal diagnosis; the optical compensation unit is used for optically correcting eye aberrations; the pupil monitoring unit is used for adjusting movement of the eyes and head and measuring the pupil change; the fixed target unit is located on a conjugate plane of the retina and used for guiding the sight direction of a subject. 本发明涉及医疗器械领域，一种多尺度混合视觉损伤分析仪，用于对扩展视网膜上感应刺激进行实时分析，包括：照明单元，用于在眼睛的不同层上提供至少一个光探针以进行眼睛分析；成像单元，用于在多尺度刺激的整个视野上捕获视网膜图像；多尺度刺激发生器单元，用于为显示多个场域控制下的超高分辨率图像，所述多尺度刺激发生器单元具有可见光灵敏度，并且能够输出可控制的模糊刺激；处理单元，用于稳定大视场刺激，进行视网膜诊断；光学补偿单元，用于光学校正眼睛像差；瞳孔监测单元，用于调节眼睛和头部移动并测量瞳孔变化；和固定目标单元，位于视网膜共轭平面，用于为引导主体的视线方向。
