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 …

Retroreflectors reflect an image or beam back 180° toward its original direction. Prisms achieve this either through total internal reflections (TIR) or specular reflections, depending on whether the …

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.

By replacing the mirrors with a hollow retroreflector or dihedral reflector, the opto-mechanics become much simpler and as in the FTIR example, will reduce linear stage errors.

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 …

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.

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, …

Retroreflectors Our retroreflectors use the corner cube method to reflect a parallel return beam back from its source. The most economic choice is a solid glass retroreflector, where the input and return …

Retroreflector Geometry Retroreflectors reflect incident light back toward the direction of the light source, operating over a wide range of angles of incidence.
