WebLight scattering, also known as Raman scattering, occurs in the optical fibre. Unlike incident light, this scattered light undergoes a spectral shift by an amount equivalent to the resonance frequency of the lattice oscillation. The light scattered back from the fibre optic therefore contains three different spectral shares: 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 specks of light to appear in the photo. This gives rise to what are sometimes referred to as orb artifacts. Photographic backscatter can result from snowflakes, rain or … 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 Backscattering can occur in quite different physical situations, where the incoming waves or particles are deflected from their original direction by different mechanisms: • Diffuse reflection from large particles and Mie scattering, causing alpenglow and gegenschein, … See more The backscattering method is also employed in fiber optics applications to detect optical faults.
