Abstract
This disclosure describes an apparatus for an optical visual display in a simulator training apparatus to develop a realistic infinity virtual image. Two spherical mirrors are positioned facing each other a multiple of their radius apart so that an image projected from above will be focused by one mirror so that an observer viewing the other of the two spherical mirrors will see an infinity virtual image. A modification of this arrangement is described also as providing a tilt in the projected image to develop a startling three-dimensional effect in the viewed image. A modification of this arrangement is described also as providing dual viewing of two differing infinity virtual images utilizing a single optical system.
