Second-harmonic imaging in random media. (English) Zbl 1378.78015
The authors study the problem of optical imaging of small nonlinear scatterers in random media. They propose a new form of coherent mesoscopic imaging where interferometric measurements are used to localize small scatterers that emit second-harmonic light. As a main conclusion, they observe that images obtained by coherent interferometric imaging are more robust to statistical fluctuations in the background medium than those of migration imaging.
