本文针对视网膜电图(ERG)检测中所存在的问题,探讨了利用微处理机实现ERG自动检测的方法,介绍了根据这些方法构成的ERG微机检测系统。该系统改进了ERG信号的引导方式;依靠计算机本身的功能,增强了系统抗干扰(特别是50Hz干扰)的能力;简化了操作,提高了检测效率。同时还在计算机上实现了EBG参数的自动测量,使EPG检测水平有了较大程度的改善,便于该技术的推广应用。
In this paper, the problems of ERG detection are discussed, and the methods of using microprocessor to detect ERG are discussed. The ERG microcomputer detection system based on these methods is introduced. The system improves the boot method of ERG signals; relying on the function of the computer itself, enhances the system anti-interference ability (especially 50Hz interference) ability; simplifies the operation and improves the detection efficiency. At the same time, the automatic measurement of EBG parameters has also been implemented on the computer, which has greatly improved the level of EPG detection and facilitated the popularization and application of the technology.
