Resolving forward scatter (IMAGE)
Caption
In a new paper published in the journal Optica, a group of researchers from Bar-Ilan University in Israel reports the first ever direct mapping of forward scattering events. The technique is implemented in a specific category of optical fibers, called “polarization maintaining”. In these fibers, a pair of light waves moving in one direction can initiate the forward scattering of a third, counter-propagating optical field. “The forward scattering of that wave is directly mapped as a function of time, just like known protocols for reflections analysis.
