Abstract

An eye tracking device for analyzing motion of an individual's eye includes an image conveyor subsystem, an image receiving subsystem, and an image processing subsystem. The image conveyor subsystem includes a flexible fiber optic image guide having a first end spaced apart from a second end by a middle portion. The image guide first and second ends are in optical communication with each other. The image guide first end is positioned at a selected location with respect to an individual's eye. The second end is interfaced with the image receiving subsystem. The image receiving subsystem includes CCD video camera. The CCD video camera converts real-time analog eye images conveyed by the fiber optic image guide into digitized representations of the eye image. These digital representations are analyzed by the image processing subsystem. The image processing subsystem includes a computer directed by included computer software. The software analyzes the digitized image and produces diagnostic feedback.
