Eye Tracking System CS681
|
|
Search coil system to detect 3D eye and head movements
|
|
|
|
|
The CS681 is the third generation of Primelec’s search
coil systems for the linear detection of 3D eye and head
movements. The system provides 8 recording channels for the
simultaneous digital processing of up to 8 search coils in
real-time. |
|
|
|
The ultra high accuracy and bandwidth guarantees
effortless recording of not only saccades, vergence, smooth
pursuit, vestibular and optokinetic eye movements but also of
miniature eye movements: drift, tremor and microsaccades. Applications include
neuro-physiological, ophthalmological,
psychological, reading, psychiatric and visual studies. |
