To address a U.S. Army need for a head- or helmet-mounted eye tracker, Physical Optics Corporation (POC) proposes to develop a novel Waveguided Holographic Infrared Soldier-mounted eye Tracker (WHIST), based on a unique integration of waveguided infrared beam eye illumination, a low-profile waveguide visor, a unique reflection hologram, and a high-speed CMOS imaging chip. The infrared beam is delivered from an LED to the eye via optical fiber by total internal reflection inside a thin plastic waveguide visor and a reflection hologram. The beam reflected from the eye and coupled into the imaging fiber bundle is captured and processed by the CMOS chip. The device will collect complete information about gaze, pupil, eyelid, and saccadic movements, and determine points of fixation of eyes in real time. In Phase I POC designed, analyzed, and fabricated a laboratory setup consisting of a waveguide visor plate with a coupling hologram and COTS components, which demonstrated the feasibility of WHIST. In Phase II POC will produce a complete prototype system; data streams will be collected, processed, and integrated with data from a standard physiological database. Human use studies will be performed according to an already approved USAARL protocol.
