Corner Cube Prism has three mutually perpendicular surfaces and a hypotenuse surface. The exterior Corner Cube Prism is equal to an optical glass cube which is cut down as its angle. Any ray entering the hypotenuse will be reflected and emerge from the entrance/exit face parallel to itself, but in the opposite direction of propagation if the three mutually perpendicular surfaces are exactly 90 degree. For its special performance, it is not only used in military affairs, aviation and spaceflight, but also used in the distance measurement, optical signal process and laser interferometer.
