Abstract
A periscope has an IR sight corresponding to the infrared light split from the optical splitters; a visible camera corresponding to the visible light split from the optical splitters; and a laser range finder corresponding to the laser beam for emitting and receiving the laser beam. The three different light beams are integrated to share a common optical path by means of a prism so as to reduce the size and the cost.
