The scleral search-coil system is the accepted standard for precise and accurate recording of eye movements in the lab and clinic. One of the drawbacks of this system is the connecting wire that leads from the eye coil to the associated electronics; this wire causes irritation to the subject and has a tendency to break during experiments. We have developed a modified version of this technique, which uses a resonant scleral coil and no connecting wire. A transmitter sends a stream of pulses to the eye coil, and a receiver then detects the resonant oscillations re-radiated from the eye coil. The relative intensity of the signal as received by sets of orthogonal receiver coils determines the orientation of the eye coil. The new approach retains the advantages of accuracy, precision, and high sample rate, while making the system portable and more comfortable.
