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.

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.

网页2013年10月7日 — A retroreflector is an optical device that returns an oncoming beam of light back to its source. It can be as simple as a tiny glass sphere or a type of prism formed from glass or plastic. (For example, you can build a Glass Bead Projection Screen.)

网页2021年9月12日 — A retroreflector doesn't reflect light in all directions like a dry road, and it doesn't reflect light away from the source like a flat mirror. Instead, a retroreflector directs the light back...
Reflectors – light, mirrors, diffuse reflectors, retroreflectors, fiber ...
网页More specifically, a retroreflector is a device which reflects light back into itself (but possibly with some spatial offset). The actual function of a reflector is often performed close to its surface, but the underlying material may still be important e.g. to provide sufficient mechanical stability and opportunities for mounting.
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. This is profoundly different from reflections at ordinary mirrors, where a light beam is reflected back in itself only for ...

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.
Retroreflectors - SPIE
网页Retroreflectors reflect incident light back toward the direction of the light source, operating over a wide range of angles of incidence. Typically they are constructed in one of two different forms, 90-deg corner cubes or high index-of- refraction transparent spheres with a reflective backing.
