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 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.

There are several different types of retroreflectors available, each with their own specific properties and applications. A common type is the corner reflector, which uses a set of three mirrors arranged in a triangular shape to reflect incoming light back to its source. The prism reflector uses a set of prisms to reflect light back to its source.

2024年5月21日 · 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. Common types include the corner cube retroreflector, which can send light back long distances and is useful on highways.

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.

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.

Retroreflectors are simple geometric conducting structures that concentrate the reflected wave back in the direction of incidence. They are capable of producing a high RCS over a wide range of aspect angles. This thesis examines the RCS performance …

They’re actually very interesting pieces of optical design. A retroreflector, or corner cube prism as we sometimes call them, is a device or surface that reflects light back to its source with a minimum of scattering. What does that actually mean? Well, think about it.

2018年11月5日 · A retroreflector is a device capable of reflecting a signal back to the source, in the same direction, with a minimum amount of scattering, over a wide range of incident...

2022年2月14日 · Retroreflection in road paint and road signs is needed to send vehicle lights back towards the driver and to increase road visibility. When a road is painted, transparent glass spheres (commonly called beads) are scattered onto …
