Related to backscattered: backward scattering


1. The deflection of radiation or particles by electromagnetic or nuclear forces through angles greater than 90° to the initial direction of travel.
2. The radiation or particles so deflected.

back′scat′ter v.


1. (General Physics) the scattering of particles or radiation, such as sound waves, X-rays, or alpha-particles, by the atoms of the medium through which they pass, in the backward direction
2. (General Physics) the radiation or particles so scattered
3. (Military) a technique whereby very long-range radars locate targets hidden by the curvature of the earth. Radar beams are reflected off the underside of the troposphere onto the target and the return beams, similarly reflected, are measured
to scatter in this way


(ˈbækˌskæt ər)

1. the deflection of radiation by scattering in a direction opposite to the direction of incidence.
2. radiation scattered in this manner.


Refers to a portion of the laser energy that is scattered back in the direction of the seeker by an obscurant. See also laser.

The subject of the public contract is field emission scanning electron microscope (SEM) designed for the observation of conductive and non-conductive materials in high resolution (micro to nanometer scale), allowing the display surface samples with high depth of field by using multiple detection (SE - backscattered electron detector, BSE - detector backscattered electrons SE and BSE detectors placed in the tube of the microscope, the original secondary electron detector for low vacuum STEM - detector transmitted electrons).
In our measurement with the correlation spectrometer the effect of electron backscattering will be even more suppressed because the backscattered electrons will be reflected again from the magnetic plug with probability about 80%.
The SEM images were obtained with an efficient backscattered electron detector (10-15 KV primary electrons).
The other patent covers a tomography system that uses backscattered X-rays to determine the depth of objects within a container, allowing three-dimensional information to be displayed in the backscatter image.
