The Angle-Meter NT is the second generation of Primelec's search coil systems for the linear detection of 3D
eye and head movements, which was introduced in 1999. The system was developed in cooperation with the Vestibulo-Oculomotor Laboratory
of the University Zurich. The system's very high accuracy and bandwidth ensures effortless recording of horizontal, vertical and torsional eye and head movements of unrestrained laboratory animals. The
system is based on Primelec's enhanced amplitude detection (FFT). A digital signal processor is used to detect the angular
orientation of the search coils and to control the unit. The completely digital controlled
Angle-Meter NT provides a wide variety of settings, nevertheless the handling
is very easy and user friendly.
