Abstract
An apparatus for a visual display in a training simulator. A projector illuminates a convex side of a spherical screen. A concave face of a spherical mirror facing the convex side of the spherical screen reflects the image on the spherical screen to a viewer. A second embodiment projects an image on a first mirror. The projected image is reflected onto a convex portion of a spherical screen. The image on the convex portion of the spherical screen is reflected to a concave mirror facing the convex face of the screen. A viewer sees the projected image on the concave mirror. The first mirror and the second mirror can be formed as one mirror.
