摘　　要：文章针对目前在眼底照相机光学性能检测中遇到的难点问题进行讨论和研究,并按照YY 0634-2008的基本测试原理设计了一套眼底照相机检测装置以尝试解决目前主要难点问题。该装置使用LED显示屏作为核心器件,通过电动升降台和计算机显示技术辅助完成分辨率、视场允差、摄影放大率和调焦范围等性能指标的测试。最后设计试验与传统的测试方法进行对比验证,结果表明该装置能够满足现阶段对眼底照相机光学性能质控的要求。This article focuses on discussing and researching difficult problems in optical performance test for fundus cameras. In order to solve these difficulties, we designed anfundus camera detection device by YY 0634-2008.The device takes the LED monitor as a core compent, through the electric lifting platform and the computer display technology aided complete resolution, allowance for viewing angle, photography magnification and focusing performance indexes such as the scope of testing.Finally, we designed experiment tocompared with the traditional test method, and the Results： show that the device can meet the requirements of the optical performance control of fundus camera.
