High Resolution, Ultrafast Oculomotor and Vestibular System

There is a growing need for reliable vestibular and oculomotor tests, to precisely define levels of vestibular/oculomotor disfunctions. Presently, eye movement is measured by several methods, including video techniques, photodiodes, search coils embedded in contact lenses, or by optical properties of the eyes. Because of its tremendous advantages, Physical Optics Corp (POC) proposes to technique to developing a high-resolution ultra-fast oculomotor and vestibular (UFOX) test system. To enhance the performance of this system, POC will include an Object-Tracking Novelty Filter (OTNF) in the final design. In Phase I, POC will concentrate on design and implementation issues for a high resolution, high speed eye tracking mechanism for UFOV testing. Phase I will demonstrate the feasibility of such a test system. This method utilizes simultaneous processing of two successive video frames, where the ith frame is a reference to the next (i+1)th frame. Tracking is ensured if the object of interest remains in the sensor's (TV camera) field-of-view, and does not change in scale or aspect within the limits of the system.
