ABSTRACT:
A real mirror image forming optical system is constructed from a half-mirror, and from a retroreflector placed in a position where it recursively reflects either the light passing through or reflected by that half-mirror, so that light emitted from an object to be projected placed behind the half-mirror can pass through either a first light path consisting of passing through the half-mirror, recursive reflection by the retroreflector, and reflection by the half-mirror; or a second light path consisting of reflection by the half-mirror, recursive reflection by the retroreflector, and passing through the half-mirror; thus by one or both of these light paths a real mirror image of the object to be projected is formed at a planar symmetric position with respect to the half-mirror surface.
