PICKUP OF HEAD MOVEMENT IN VESTIBULAR REFLEX EXPERIMENTS WITH AN OPTICAL-FIBER GYROSCOPE

We show that, in studying eye-head coordination, the rotation of the h ead can be measured with the aid of a fiber optics gyroscope mounted o n a helmet worn by the subject, and that the performances of this appr oach are considerably better than those of currently used sensors, Aft er presenting the specifications required in head rotation measurement s, we report details on the used gyroscope and on its interconnection to the acquisition system and discuss experimental results of head rot ation measurements made by the gyroscope and the potentiometer sensor.
