【摘要】：眼睛是人體感知光線、接收外界信息的主要器官,眼的器質性病變將直接影響信息交換,從而給病患的生活和工作帶來極大不便。而眼底血管的病變又是判斷多種疾病的依據,眼底檢查具有重要的臨床意義。本文根據臨床眼底檢查要求,在傳統直接檢眼鏡和眼底照相機基礎上,設計了便攜式數字檢眼鏡。在系統設計中,對光學系統進行了優(yōu)化設計,采用中空反射鏡形成環(huán)形照明光源,解決了角膜反射光和雜散光問題。在成像系統設計上,運用ZEMAX軟件對成像系統進行設計優(yōu)化,成像物鏡全部用球面,提高了系統的性價比。并通過補償鏡設計,保證了眼底圖像以平行光射出。系統滿足了檢眼鏡小型化和圖像數字化處理要求,實現了眼底圖像的顯示、存儲和后期圖像處理。
[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.
