Relevance of temporal coherence in the second-harmonic cross-correlation measurement of a multiply scattered laser pulse
- 35 Downloads
Second-harmonic cross-correlation operates a selection in time-phase among the randomly dephased contributions to an optical field that propagated through a scattering medium. It can thus be used to selectively detect the weak contribution remaining coherent with the incident field.
