In physics, backscatter (or backscattering) is the reflection of waves, particles, or signals back to the direction from which they came. It is usually a diffuse reflection due to scattering , as opposed to specular reflection as from a mirror , although specular backscattering can occur at normal incidence with a surface.
Backscatter technology produces an image that resembles a chalk etching. [1]Backscatter X-ray is an advanced X-ray imaging technology. Traditional X-ray machines detect hard and soft materials by the variation in x-ray intensity transmitted through the target.
The waves are scattered many times while traveling through the medium. Even for incoherent radiation, the scattering typically reaches a local maximum in the direction of backscattering. For coherent radiation, however, the peak is two times higher. Coherent backscattering is very difficult to detect and measure for two reasons.

For electron backscattering diffraction microscopy, a flat polished crystalline specimen is usually placed inside the microscope chamber. The sample is tilted at ~70° from Scanning electron microscope (SEM) flat specimen positioning and 110° to the electron backscatter diffraction (EBSD) detector. [3]
Ambient backscatter [1] uses existing radio frequency signals, such as radio, television and mobile telephony, to transmit data without a battery or power grid connection.. Each such device uses an antenna to pick up an existing signal and convert it into tens to hundreds of microwatts of electrici
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science.Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
Wine glass in LCD projectors light beam makes the beam scatter.. In physics, scattering is a wide range of physical processes where moving particles or radiation of some form, such as light or sound, are forced to deviate from a straight trajectory by localized non-uniformities (including particles and radiation) in the medium through which they pass.
