Wavefront Aberrations
... (like V = U + P). In reality, many of the rays that are incident on a lens are NOT paraxial. So, ideal images are NOT formed. We can begin to see the effects of this if we expand the sine function in a power series expansion: sin = 3/3! + 5/5! .... In the paraxial approximation, we keep just ...

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.
