GaAs pillars were fabricated on a fused silica substrate and the spectrum of the backscattered radiation … The backscattering method is also employed in fiber optics applications to detect optical faults. Light propagating through a fiber optic cable gradually attenuates due to Rayleigh scattering. Faults are thus detected by monitoring the variation of part of the Rayleigh backscattered light. Since the backscattered light … See more 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 … See more The term backscatter in photography refers to light from a flash or strobe reflecting back from particles in the lens's field of view causing … See more Backscattering can occur in quite different physical situations, where the incoming waves or particles are deflected from their original direction by … See more • Forward scattering • Scattering • Backscatter X-ray (in security scanning applications, e.g. at airports) • Backscatter (email) See more
