Corner Cube Retroreflector
Corner Cube Retroreflector
shared：
A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects waves back directly towards the source, but translated. The three
intersecting surfaces often have square shapes. Radar corner reflectors made of metal are used to reflect radio waves from radar sets. Optical corner reflectors, called corner cubes, made
of three-sided glass prisms, are used in surveying and laser rangefinding.
