【摘要】:眼睛是人体感知光线、接收外界信息的主要器官,眼的器质性病变将直接影响信息交换,从而给病患的生活和工作带来极大不便。而眼底血管的病变又是判断多种疾病的依据,眼底检查具有重要的临床意义。本文根据临床眼底检查要求,在传统直接检眼镜和眼底照相机基础上,设计了便携式数字检眼镜。在系统设计中,对光学系统进行了优化设计,采用中空反射镜形成环形照明光源,解决了角膜反射光和杂散光问题。在成像系统设计上,运用ZEMAX软件对成像系统进行设计优化,成像物镜全部用球面,提高了系统的性价比。并通过补偿镜设计,保证了眼底图像以平行光射出。系统满足了检眼镜小型化和图像数字化处理要求,实现了眼底图像的显示、存储和后期图像处理。
[Abstract]:The eye is the main organ that the human body perceives the light and receives the outside information. The organic pathological changes of the eye will directly affect the information exchange, which will bring great inconvenience to the life and work of the patient. The fundus vascular lesion is the basis for judging many diseases, fundus examination has important clinical significance. A portable digital ophthalmoscope was designed on the basis of traditional direct ophthalmoscope and fundus camera according to the requirements of clinical fundus examination. In the system design, the optical system is optimized and the circular illumination source is formed by the hollow reflector, which solves the problem of corneal reflection and stray light. In the design of the imaging system, the ZEMAX software is used to optimize the design of the imaging system, and the imaging objective is all spherical, which improves the performance and price ratio of the system. Through the design of compensation mirror, the fundus image can be shot out with parallel light. The system meets the requirements of ophthalmoscope miniaturization and image digitization, and realizes the display, storage and post-image processing of the fundus image.
