Corner Cube Retro-Reflector
|
Corner Cube Retro-Reflectors have three mutually perpendicular surfaces
and a hypotenuse face. It operates on the principle of total
internal reflection(TIR). A beam entering the effective aperture is
reflected by the three roof surfaces and emerges from the entrance/exit
surface parallel to itself. This property is independent of
orientation of the retro-reflector, within acceptance angle
limitations. For applications in which either the acceptance angle
for TIR is exceeded, or the reflecting surfaces can not be kept
sufficiently clean for TIR, a metal or dielectric coating can be applied
to the reflecting surfaces.
