Viewing a Corner Cube Prism: what one sees when looking in to a retro-reflector prism ?. A light ray entering a mirrored corner cube prism always exits along a parallel path- but how would a camera capture this experience? Did I fool you? The geometry of a trihedral retroreflector is simply the corner of a cube, and arrays of corner-cubes like this one were placed on the Moon by Apollo astronauts to allowing precise measurement of the Earth-Moon distance by bouncing powerful laser pulses back to Earth observatories.

Corner Cube Prism: a light ray entering a mirrored retro-reflecting prism always exits along a parallel path. The complete path in the prism can be seen with a 405nm UV laser beam which is made visible via fluorescence of dopant chemicals (such as Pb, Mn, and Zn) often added to create optical glass.
