<p>@ Apparatus for recording eye movement. A light source has its rays directed toward the eye of a subject and a glass dome (35) secured to spectacle frames worn by the subject. The primary and secondary glints reflected off the glass (35) and eye cornea, respectively, are transmitted via mirrors (36, 37, 38, 41), lenses (39) and a fiber optic image guide (25) to a video camera tube (26). The position of the glints on an XY axis is electronically determined and the information is fed to a computer which compares the data from the two glints and compensates forthe head movement which corresponds to movement of the primary glint.</p> |
