Abstract

The design and use of an on-line PDP 11/40-based system for quantitative study of ocular kinetics are described. The system can be used in neurophysiological or ophthalmological applications. Two different techniques are presented. In one, horizontal, vertical or oblique eye motion can be studied, in the other horizontal eye motion only. Several parameters of eye motion can be measured including saccadic velocity, eye movement latency and accuracy of refixation. For ophthalmological EOG applications the system allows measurement of the absolute voltage excursion corresponding to a horizontal eye movement of a specific amplitude. The system consists of five software programs and supporting signal processing equipment. The software package runs under the RSX11M executive.

摘要

本文描述了一种基于在线PDP 11/40系统的设计与应用，用于眼部动力学的定量研究。该系统可用于神经生理学或眼科应用。文中介绍了两种不同的技术。一种技术可用于研究水平、垂直或斜向的眼球运动，另一种技术仅用于研究水平眼球运动。可以测量眼球运动的几个参数，包括扫视速度、眼球运动潜伏期和再注视准确性。对于眼科EOG应用，该系统允许测量与特定幅度的水平眼球运动相对应的绝对电压偏移。该系统由五个软件程序和支持信号处理设备组成。软件包在RSX11M执行程序下运行。
