WebApr 12, 2024 · So the search is on for new ways to reduce the backscattering, or even prevent it entirely. A one-way street for photons is impossible today. One suggestion for minimizing the loss of photons in an integrated photonic system is to guide the light through the circuit using topological interfaces that prevent backscattering by design. 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
