1. A cube corner retro-reflector, comprising:
- three mutually perpendicular reflecting planes arranged in a pyramidal configuration,wherein at least one of the reflecting planes has a non-isotropic surface causing a polarization state of a ray exiting the cube corner retro-reflector to be orthogonal or substantively orthogonal to a polarization state of a ray entering the cube corner retro-reflector for all linear polarization orientations.

10. A detecting system for detecting changes in an irradiance beam, comprising:
-
an optical source configured to create an irradiance beam; a polarized beam splitter having first and second sides and configured to receive the irradiance beam from the optical source into the first side; a cube corner retro-reflector configured to receive the resultant beam from the first side of the polarized beam splitter and to retransmit the beam to the second side of the polarized beam splitter, the cube corner retro-reflector including three mutually perpendicular reflecting planes arranged in a pyramidal configuration, wherein at least one of the reflecting planes has a non-isotropic surface causing a polarization state of a ray exiting the cube corner retro-reflector to be orthogonal or substantively orthogonal to a polarization state of a ray entering the cube corner retro-reflector for all linear polarization orientations; and a detector unit configured to detect changes in the irradiance beam received from the second side of the polarized beam splitter. - View Dependent Claims (11, 12, 13, 14, 15, 16)
