Abstract
The invention contemplates a periscope mirror system wherein viewing on a selected one of two 180.degree.-opposed viewing axes is provided to a single exit-mirror for directing exit light in the same direction regardless of the selected viewing axis. The entrance mirror and the exit mirror are angularly positionable on parallel pivot axes which for a first direction of viewing involve direct reflection from the entrance mirror to the exit mirror, and which for the opposite direction of viewing involve indirect reflection from the entrance mirror to the exit mirror via an intermediate image-erecting third mirror.
