ABSTRACT:
A direct vision periscope is disclosed having a second set of mirrors strategically positioned within a wide angle trapezoidal periscope. The main optical path has a vertical field of view of 24° above and below horizontal while the secondary optical path provides a field of view of 12° to 59° above horizontal to allow the occupants to see elevated areas. When used on military vehicles, multiple periscopes may be disposed about the operator's compartment to create a near panoramic view.
