A set of three mutually perpendicular reflective surfaces, placed to form the internal corner of a cube, work as a retroreflector. The three corresponding normal vectors of the corner's sides form a basis (x, y, z) in which to represent the direction of an arbitrary incoming ray, [a, b, c].
A modulating retro-reflector (MRR) system combines an optical retro-reflector and an optical modulator to allow optical communications [1] and sometimes other functions such as programmable signage. [2] Free space optical communication technology has emerged in recent years as an attractive alternative to the conventional radio frequency (RF ...
Many different colors and degrees of reflection intensity are provided by numerous manufacturers for various applications. As with any retroreflector, sheeting glows brightly when there is a small angle between the observer's eye and the light source directed toward the sheeting but appears nonreflective when viewed from other directions.

Daylighting is the practice of placing windows, skylights, other openings, and reflective surfaces so that direct or indirect sunlight can provide effective internal lighting. Particular attention is given to daylighting while designing a building when the aim is to maximize visual comfort or to reduce energy use.
The Laser Ranging Retroreflector (LRRR) is the first ever deployable lunar laser ranging experiment.It was carried on Apollo 11 as part of the Early Apollo Scientific Experiments Package, and on Apollo 14 and Apollo 15 as part of the Apollo Lunar Surface Experiments Package (ALSEP).
