There are several different types of retroreflectors such as Corner Cube, Cat’s Eye, Phase Conjugate Mirror, etc. Retroreflectors are used in situations where there is a need to reflect the light back to the source with minimal deflection. Applications include free-space optical communications networks, satellite tracking as well as laser spectroscopy experiments. A key property of the corner-cube reflector is that the entering ray is reflected back with a precisely inverted independent of the angle of incidence.
