Binocular helmet-mounted displays have become increasingly popular over the past several years; particular emphasis has been placed on achieving wide field of view displays with resolution capability greater than that attainable with a monocular system utilizing a single CRT. Binocular display systems with severely divergent axes have been developed wherein the horizontal field is divided into three areas, that visible to the right eye only, that visible to the left eye and an overlap region. A typical system has individual displays with 80 degree fields of view with axes turned outward ±20 degrees achieving a total field of 120 degrees with a 40 degree overlap. The turnout of the optical axes means that the center of the display field is 20 degrees off-axis in the individual displays. Almost all points in the overlap regions are at significantly different off-axis angles in the two displays. The implications of these factors relative to required aberrational correction and system characteristics are discussed.
