Incoherent vs coherent scattering

WebFeb 15, 2006 · Until recently, the biological literature on structural colour has obscured the most fundamental physical distinction among all mechanisms of structural colour production: incoherent vs coherent scattering (e.g. Prum and Torres, 2003a; Prum and Torres, 2003b; Prum and Torres, 2004).Incoherent scattering is the differential scattering … Webwhere σ pe is the atomic photoeffect cross section, σ coh and σ incoh are the coherent (Rayleigh) and the incoherent (Compton) scattering cross sections, respectively, σ pair and σ trip are the cross sections for electron-positron production in the fields of the nucleus and of the atomic electrons, respectively, and σ ph.n. is the photonuclear cross section.

WebYes, coherent radiation means that the phases of two ( or more ) waves representing the radiation differ by a known constant. Incoherence means that the phase differences are unknown/random. Laser radiation is coherent because stimulated emission assures phase differences are constant . WebEven 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. …
