摘　　要：目的 探索检影镜数字化视频系统的研制方法,为以后的相关开发研究和产品化莫定基础.方法 通过自制光学适配器来改造现有的检影镜光路 通过整合光学镜头、电荷耦合元件（CCD）和采集卡来改造电路 通过自主开发相应的软件来实现视频/图像和验光结果的捕获、存储和检索.结果 检影镜数字化视频系统的研制获得成功.通过该系统可以实现检影影动的同步示教、影动视频和验光结果的存储和检索功能.结论 通过对现有检影镜的光路和电路进行改造,结合软件开发可以实现检影镜数字化视频系统的研制.Objective To develop a digital video system for retinoscopy and to lay a foundation for related research and development. Methods An optical adapter was created to transform the optical path images of a retinoscope. The electronic circuit performed the transformation by integrating the appropriate optical lenses with a charge-coupled device （CCD） and video capture card. The digital video was saved and reviewed by a newly developed video capture program and management system.Results The digital video system for retinoscopy was successfully created. A synchronization demonstration could be performed and the system could meet the demand for digital video.Conclusion By using an electronic circuit for transforming the optical images of retinoscopy and developing a software program, a digital video system for retinoscopy can be successfully created.
