Abstract: A housing has a hollow section, and openings are formed at both ends of the hollow section so as to communicate with the outside. An aperture is formed in the internal wall of the housing so as to oppose the opening, and a video camera is fitted into the opening. A half mirror, a mirror, an optical lens, and light sources are disposed within the hollow section. The light sources are alternately illuminated while a patient wears equipment having such a construction. Light reflected from one eye passes through the half mirror and enters a light receiving surface of the video camera. On the other hand, light reflected from the other eye is reflected from the mirror and a half mirror and, then, enters the light receiving surface of the video camera. The optical lens corrects an error arising from a difference in length between two optical paths.

Abstract: An eye movement analysis system projects imaging light to an eyeball for a time duration short enough so as not to create blurring. Image data is then recorded onto a recording medium. The image data is then read out of the recording medium and used to calculate positional data concerning the eyeball's present location. At a later time, image data of the eyeball is again recorded in the recording medium and read out to calculate positional data concerning the eyeball's new location. The two sets of positional data are used to calculate eye movement data for use in diagnosing the causes of vertigo and/or disequilibrium.
