The portion of light in a fibre that is redirected to that it travels in the opposite direction from the direction of intended transmission.
the deflection of particles or radiation by scattering processes through angles greater than 90 degrees with respect to the original direction of motion
The process of scattering or deflecting into the sensitive volume of a measuring instrument radiation that originally had no motion in that direction. The process is dependent on the nature of the mounting material, the shield surrounding the sample and the detector, the nature of the sample, the type of energy of the radiation, and the geometry. See also scattering.
The scattering of light in a direction opposite the original one.
Refers to light diffraction at microscopic non-uniformities in the index of refraction of the fiber causing backreflection of optical power towards the source.
The scattering of light in a fiber back toward the source, used to make OTDR measurements. Bandwidth: The range of signal frequencies or bit rate within which a fiber optic component, link or network will operate.
Reflecting light back in the direction of the source.
Radio wave propagation in which the direction of the incident and scattered WAVES, resolved along a referenced direction (usually horizontal), are oppositely directed. A signal received by backscattering is often referred to as BACKSCATTER. [] See also SCATTERING, RADAR SCATTERING.

Light scattered from particles scattered at angles greater than 90 degrees with respect to the incident direction of the source as it impinges on particles in the water. Backscattering is particularly useful in application that tie remote ocean color images from satellites and planes to in-water optical processes.
Process by which up to 25% of radiant energy from the sun is reflected or scattered away from the surface by clouds. Serves the greatest importance in the Atmospheric Heat Budget. Large errors in the assumed value of this variable may have important effects on computer models of the atmosphere.

Matthews; 173; 1971; Colonial; Baltimore.
Energy, when hitting a target, can be scattered in many directions. The part of the energy that is scattered back in the exact direction where it came from, is "backscattered". (Related word: reflection)
Portion of solar radiation directed back into space as a result of particle scattering in the atmosphere.
The re-reflection of thermal energy generated on the ground and reflecting off the underside of clouds or inversion layers. Also can refer to unwanted front surface reflections off of a transparent optical element.
The return of a portion of scattered light to the input end of a fiber; the scattering of light in the direction opposite to its original propagation.
The scattering of radiant energy into the hemisphere of space bounded by a plane normal to the direction of the incident radiation and lying on the same side as the incident ray; the opposite of forward scatter. Atmospheric backward scatter depletes 6%–9% of the incident solar beam before it reaches the earth's surface. In radar usage, backscatter refers only to that radiation scattered at 180° to the direction of the incident wave.
