Abstract

The design of a two-dimensional (2D) magnetic field search coil system based on the phase detection principle is described. The system was developed to record horizontal and vertical eye and head movements of small, unrestrained laboratory animals. It is also applicable for measuring three-dimensional (3D) eye and head movements in primates and man. The output is linear over 355 degrees in the horizontal plane and over +/- 60 degrees in the vertical direction. The procedure of recording 3D eye and head movements is discussed.

摘要

本文描述了基于相位检测原理的二维（2D）磁场搜索线圈系统的设计。该系统旨在记录小型、不受约束的实验动物的水平和垂直眼动及头部运动。它也适用于测量灵长类动物和人类的三维（3D）眼动及头部运动。其输出在水平面上355度范围内呈线性，在垂直方向上在±60度范围内呈线性。文中还讨论了记录三维眼动及头部运动的过程。
