Polarization Study 1 Introduction
... In many circumstances, we need to control the polarization of beams accurately (say for example to obtain optimal contrast in an interferometer). There are a number of optical elements that can be used for this purpose. Their common feature is to introduce a phase change between two orthogonally pol ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
