Device that reflects light back
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects radiation (usually light) back to its source with minimum scattering. This works at a wide range of angle of incidence, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, … See more There are several ways to obtain retroreflection: Corner reflector A set of three mutually perpendicular reflective surfaces, placed to form the internal corner of a … See more Many prey and predator animals have naturally retroreflective eyes by having a reflective layer called the Tapetum lucidum behind the retina, since this doubles the light that their retina receives.
