线圈系统已经成为测量眼球运动的标准。这些系统被设计为在低频(20 KHz)下工作，通常需要较大的磁场线圈，以便在眼圈线圈位置建立均匀的磁场。这种结构使得研究自由活动动物的眼球运动几乎是不可能的。本文描述了一种工作在射频(10 MHz)的线圈系统的设计。该系统允许使用半径为10 mm的紧凑型线圈，能够在无头运动期间准确测量三维眼球运动。该系统为在多种条件下研究自由活动猴子的眼球运动提供了可能。
Coil systems have been a standard for measuring eye movements. These systems, which have been designed to work at low frequencies (20 KHz), generally require large field coils so that a uniform field can be established at the eye coil site. This configuration makes it virtually impossible to study eye movements in freely moving animals. In this paper, we describe the design of a coil system, which operates at radio frequencies (10 MHz). This system allows the use of compact coils with radii of 10 mm that are capable of accurately measuring eye movements in three dimensions during head free locomotion. This system opens the possibility for studying eye movements in freely moving monkeys under a wide range of conditions
