A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light or other radiation back to its source with minimum scattering.

The first practical retroreflector was invented in 1934 by engineer Percy Spencer, who used a series of prisms to create a highly visible marker that could be seen from long distances even in low-light …

Fiber optic retroreflector patch cables reflect light input through the connector backward through the fiber and can be used to create a fiber interferometer or to build a low-power fiber laser.

A retroreflector is an optical device that reflects light back in a direction parallel to the incident beam. This behavior is maintained over a range of incidence angles, unlike with an ordinary mirror.

The peak op2cal cross-‐sec2on rises rapidly as the retroreflector diameter to the fourth power. For the popular 1.5 in (38 mm) diameter cube, the peak cross-‐sec2on is about 5.8 x 107 m2.

In scientific research, improved retroreflector designs could facilitate better data collection methods, such as precise distance measurements in geodesy or enhanced visibility in astronomical observations.

Retroreflectors: Understanding Their Functionality and Applications Introduction to Retroreflectors Retroreflectors are optical devices that reflect light back towards its source in a parallel direction to …

Aug 7, 2023 · A retroreflector is an optical device designed to reflect light back toward its source with minimal scattering. Unlike mirrors, lenses, or prisms that disperse or refract light in various directions, …

May 21, 2024 · A retroreflector reflects incoming light and directs it back to its source. The light is reflected parallel to the direction it came from, but in the completely opposite direction.

Jun 20, 2008 · A retroreflector is defined as an optical device that reflects incident light back towards its source with minimal scattering, commonly used in applications such as free-space optical …
