Chapter 2 Optical fibers
... Most optical fiber consist of a cylindrical piece of glass surrounded by an acrylic (made from a thermoplastic resin) jacket. The glass consists of a core, of refractive index n1, and a surrounding cladding, of refractive index n2, with n1 > n2. The index of the jacket is such that any light reachin ...

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.
