Abstract

An automated system is presented for on-line capture and processing of the analog signal obtained in response to light or X-ray stimulation of isolated rat retina maintained in survival by perfusion. The most important part of the system is a microcomputer Apple II (48 K Europlus) equipped with interface boards. Basic and assembler programs automatically deliver light or X-ray stimulation every 5 min. Data capture and data processing are carried out following each retinal response. Calculated parameters of the ERG, and 200 values obtained after sampling of an ERG are placed in a data file on a floppy disc. One hundred ERGs can be stored in this way.

摘要

本文介绍了一种自动化系统，用于在线采集和处理模拟信号。该模拟信号是通过对灌注维持存活的离体大鼠视网膜进行光刺激或X射线刺激而获得的。该系统最重要的部分是一台配备接口板的苹果II型微型计算机（48K欧洲版）。基本程序和汇编程序每5分钟自动发出一次光刺激或X射线刺激。每次视网膜反应后进行数据采集和数据处理。计算得到的视网膜电图参数以及视网膜电图采样后获得的200个值被存入软盘上的数据文件中。通过这种方式可以存储100次视网膜电图。
