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.
