Lab 11 - Optical Ray Tracing
... Ray tracing is a way of generating optical path in a system based on the laws of geometric optics. By successively applying the laws of reflection and refraction on the optical surface (lens, mirror, screen, iris, etc.), a light ray can be propagated from the source to they target and thereby genera ...

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.
