Satellite radar backscatter contains unique information on land surface moisture, vegetation features, and surface roughness and has thus been … 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 … Ver mais 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 … Ver mais 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, … Ver mais 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 … Ver mais • Forward scattering • Scattering • Backscatter X-ray (in security scanning applications, e.g. at airports) • Backscatter (email) Ver mais darna new character
