Retroreflector - Wikipedia
网页A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects radiation (usually light) back to its source with minimum scattering.
Retroreflectors - Thorlabs
网页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 reflective faces are coated.
Laser Ranging Retroreflector - Wikipedia
网页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).
List of retroreflectors on the Moon - Wikipedia
网页Retroreflectors are devices which reflect light back to its source. Six were left at six sites on the Moon by three crews of the Apollo program, two by remote landers of the Lunokhod program, and one by the Chandrayaan program. [1]
Retroreflectors – corner reflectors, prisms, cat eye reflector ...
网页Retroreflectors are a kind of reflectors (optical devices which reflect light), where the reflected light propagates in a direction which is parallel to the incident beam – and this for some range of beam directions.
Reflecting on retroreflectors: Applications, types, and benefits ...
网页Back on Earth, retroreflectors are commonly used in transportation applications, such as road signs, traffic cones, and “cat’s eye” markers on roads. These markers use a combination of prisms and reflective materials to create a highly visible marker that can be seen from long distances, even in low-light conditions.
How Do Retroreflectors Give You Super Vision at Night? - WIRED
网页2021年9月12日 · Instead, a retroreflector directs the light back towards the source. Yes, if you shine a light at a mirror with a 0° angle of incidence—right towards the mirror—it will come straight back at ...
What is a Retroreflector? - GoPhotonics.com
网页2023年8月7日 · 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 ensure that incoming light is directed back to its origin.
Planar metasurface retroreflector - Nature Photonics
网页2017年6月19日 · Optical retroreflectors are desirable in laser tracking 17 and for integration with planar modulators to realize modulating retroreflectors. A modulating retroreflector uses power from the...
Optics & Photonics News - How Retroreflectors Really Work
网页How Retroreflectors Really Work. Retroreflectors, which reflect light from automobile headlamps back in the same direction from which the light originated, are invaluable safety devices. They are entirely passive, requiring no power supply or maintenance.
